All About Derechos

The past several weeks have seen a good number of significant storms that have produced high winds along with associated damage. Today's forecast includes the potential for significant storms that may be severe and could bring damaging winds, hail and the possibility of flooding.

Usually when the potential for damaging winds are brought up, residents across the metro area think back to almost four years ago when the region was hit by the Ohio Valley/Mid-Atlantic Derecho. This storm brought widespread damage and disruption that took several days to recover from.

With all of the above in mind, we thought a good topic for today's 101 Days of Summer Safety would be to learn more about Derechos. Also timely as Derechos in the United States are most common in the late spring and summer (May through August), with more than 60% occurring May through July.

Since we are no experts in the field, we highly recommend that you go to the experts at the National Oceanic and Atmospheric Administration.

Go here to learn All About Derechos.

The safety tips and preparation are the same as for any significant weather event. Be prepared and be aware. Please take a moment to review some important related tips below.

It’s Hurricane And Summer Storm Season! Are You Ready?

Our main theme for today’s 101 Days of Summer Safety is Storm Preparedness. This is especially important in light of the potential for significant storms this weekend (see graphic below).
National Weather Service graphic of weather for next 3 days

Please take a moment to review the important information, via our partners in safety at the Montgomery County Office of Emergency Management and Homeland Security, on what to do before, during and after a Hurricane or summer storm.

Also take a moment to sign up for Alert Montgomery, Montgomery County’s emergency warning system, to receive important notifications of weather watches, warnings and other emergency information. Go here to sign up: https://alert.montgomerycountymd.gov

Storm Preparedness Tips:

Before a Storm

·         Build an Emergency Supply Kit, which includes such items as non-perishable food, water, a battery-powered or hand-crank radio, extra flashlights and batteries.
·         Make a Family Emergency Plan. Your family may not be together when disaster strikes, so it is important to know how you will contact one another, how you will get back together and what you will do in case of an emergency.
·         Continually monitor the media (radio, TV or internet) – Be aware of storms which could impact your area.
·         Know how you will be warned in an emergency…Alert Montgomery, (NOAA Weather radios with a tone alert are a good option)
·         Ensure your home is ready. Bring in or secure outdoor items that could become projectiles in high wind.
·         Turn the refrigerator and freezer to the coldest setting in anticipation of a power outage. Open the door only when necessary and close quickly. Frozen food in a half-full freezer should remain safe for up to 24 hours, and in a full freezer, up to 48 hours.

During a Storm
·         Follow instructions and emergency advice from County officials or heed shelter or evacuation requests made through announcements on radio/television.
·         Keep an eye on the sky. Look for darkening skies, flashes of light or increasing wind. Listen for the sound of thunder. If you can hear thunder, you are close enough to be struck by lightning.
·         Blowing debris or the sound of an approaching tornado may alert you. Tornado danger signs include a dark, almost greenish sky; large hail; a large, dark, low-lying cloud or a loud roar, similar to a freight train.
·         Gather family members, bring pets indoors and have your emergency supply kit ready.
·         Close outside doors and window blinds, shades or curtains. Close all interior doors. Stay away from doors, windows and exterior walls. Stay in a shelter location (small interior room, closet, or hallway on the lowest level) until the danger has passed.
·         During lightning, do not use wired telephones, touch electrical appliances or use running water. Cordless or cellular telephones are safe to use.
·         During a power outage use flashlights and battery-powered lanterns for light. Avoid using candles which pose a fire risk.
·         Ensure a supply of water for sanitary purposes such as personal cleaning and flushing toilets. Fill a bathtub or other large container with the water. This is particularly important for those whose water runs off of an electrical system.
·         If your residence could flood, store valuable and personal papers in a waterproof container.
·         Do not walk through flowing water. Drowning is the number one cause of flood deaths. Six inches of swiftly moving water can knock you off your feet.
·         Stay indoors and limit travel to only absolutely necessary trips. Listen to radio/television for updates. Do not attempt to drive through a flooded road – you can become stranded or trapped.

After a Storm 
·         Stay off roads to allow emergency crews to clear roads and provide emergency assistance.
·         Help injured or trapped persons. Do not attempt to move seriously injured persons unless they are in immediate danger of death or further injury.
·         Use the telephone only for emergencies.
·         Use care around downed power lines. Assume a downed wire is a live wire.
·         Watch out for overhead hazards such as broken tree limbs, wires and other debris.
·         Avoid walking into flood waters. The water may be contaminated by oil, gasoline or raw sewerage, contain downed power lines or animals.
·         Look for hazards such as broken/leaking gas lines, damaged sewage systems, flooded electrical circuits, submerged appliances and structural damage. Leave the area if you smell gas or chemical fumes.
·         Clean everything that gets wet. For food, medicines and cosmetics; when in doubt, throw it out.
·         Make sure backup generators are well ventilated. Never use grills, generators or camping stoves indoors.
·         Call 311 (or 240-777-0311 from a cell phone or from a location outside of Montgomery County) to report downed trees on public property and for help with County services, or go to mc311.com. If wires are involved with the downed tree, if anyone is trapped, or the tree is blocking a roadway, call 9-1-1.

Look Before You Lock! Heatwave Can Be Especially Dangerous For Children

When temperatures rise, so does the risk of an unimaginable tragedy – children accidentally left in hot cars. Nationally, the number of children who have died in cars as a result of the heat has already DOUBLED compared to the same time last year. Montgomery County Fire and Rescue is teaming up with Safe Kids Worldwide to prevent child deaths and injuries in hot cars.
 
When outside temperatures are in the low 80s, the temperature inside a vehicle can reach deadly levels in only minutes even with a window rolled down two inches. With sustained and record-breaking temperatures predicted in the region, families are reminded that one of the greatest dangers is leaving a child in a car unattended on a hot day. Children’s bodies do not acclimate to the heat as well as adults and can overheat easily. Infants and children under four years old are at the greatest risk for heat-related illness.

Hard Facts

Heatstroke is the leading cause of non-crash, vehicle-related deaths for children. On average, every 10 days a child dies from heatstroke in a vehicle. Children can also sustain injuries from hot cars that include permanent brain injury, blindness and loss of hearing. Heatstroke tragedies often occur when there has been a change in a family’s daily routine, a parent leaves a child in the car “for just a minute” unaware how quickly the temperature in a car can rise to dangerous levels or after a child gets into an unlocked vehicle to play unbeknownst to the parent or caregiver.

Top Tips
These tragedies are preventable. Avert and reduce the number of deaths from heatstroke by remembering to ACT:
A: Avoid heatstroke-related injury and death by never leaving your child unattended in a car, not even for a minute. Make a habit of looking in the vehicle – front and back – and keep keys stored out of a child’s reach and car doors locked when the vehicle is not in use to prevent children from getting in on their own.  
C: Create reminders by putting something in the back of your car next to your child such as a briefcase, a purse or a cell phone that is needed at your final destination. This is especially important if you’re not following your normal routine. 
T: Take action. If you see a child alone in a car, call 911. Emergency personnel want you to call. They are trained to respond to these situations. One call could save a life.

Storm Tips and Social Media Update

Montgomery County fire officials are providing the following tips and are asking residents to plan ahead, be ready and be safe:  

Stay informed by monitoring TV news, radio, the National Weather Service and the internet as storm information is updated throughout the day that may affect you and your family.

Sign up for Alert Montgomery to receive text alerts and emergency information as Montgomery County Fire and Rescue social media platforms will be operating at various points throughout the storm however will not
be a 24-hour source of timely EMERGENCY information.

For this weather event on Twitter, use the hashtag #mocostorm

The primary social media platforms used will be:
Safety Tips
  • Ensure your cell phones, laptops, tablets and other important devices are fully charged BEFORE the storm.
  • Make sure you secure, or bring inside, any loose items that could become dangerous projectiles in high winds.
  • Stay prepared by getting your emergency preparedness kit out and having a ready supply of essential items (food, water, batteries, flashlights, battery-operated radio, blankets, etc.).
  • It’s a great time to make sure the batteries in your smoke alarm and carbon monoxide alarm are fresh. Test all smoke alarms to ensure they are working.
  • If possible, stay off the roads and heed the advice of local officials. These are serious conditions that are often underestimated and can make driving, and even walking, very hazardous.  Occupants of cars and trucks also are vulnerable to being hit by falling trees and utility poles. Further, high profile vehicles such as semi-trailer trucks, buses, and sport utility vehicles may be blown over. 
  • Stay Inside and away from windows.  Go to a basement if you have one.
  • Listen to the authorities. Remain indoors until an official "all clear" is issued.
  • Use extreme caution when cleaning up storm damage on your property.  Downed or damaged power lines can send electrical currents through tree branches and metal fences, so survey the area carefully.  Use extreme caution around downed or damaged power lines. Do not remove fallen tree limbs or other debris from power lines, never drive over down lines and treat all wires – even those that are hanging or down – as if they are “live” (energized) and call 911 to report them.
  • For downed trees on public property, Montgomery County residents should call -311 between 7 a.m. and 5 p.m. weekdays (or 240-777-0311 from outside the county or from a cell phone), or file a report at http://www.montgomerycountymd.gov/311. If live wires are involved, the tree is blocking a roadway, the tree is on a structure or if anyone is trapped under a fallen tree, call 911.
  • Do NOT use candles for lighting. Using candles during a power outage poses an extreme risk of fire. Use flashlights or battery-powered lighting options and make sure you have a battery-operated radio to keep up-to-date.
  • If you are using a generator, make sure it is in a well-ventilated area to reduce the risk of breathing harmful fumes. Never place a generator under an open window and follow all manufacturer instructions.
  • Reach out to your neighbors who may need help, especially those that are elderly, disabled or infirmed.
  • Know your limits. Many storm-related deaths and injuries involve existing health problems exacerbated by the physical demands of cleanup activities.
  • Drive with caution. Avoid areas subject to flooding, including low spots, canals and streams. Do not attempt to drive on a flooded road, which could lead to becoming stranded or trapped because the depth of the water and the condition of the road is not always obvious.
  • Treat all intersections where traffic lights are out as a four way stop.
  • Please only call 911 for emergencies. Crews will be in high demand throughout the storm. If you do not have a life-threatening emergency, call 311 for assistance.

Signs and Symptoms of Heat Exhaustion and Heat Stroke


Another scorcher today!  Over the last couple of weeks, we at MCFRS have preached to everyone to stay cool and stay hydrated.  Hopefully, everyone will be able to do that.

Just in case, I thought it would be useful to post the signs and symptoms of Heat Exhaustion and Heat Stroke.  Warning signs can vary among individuals but common signs of heat exhaustion or heat stroke may include: 

Heat Exhaustion: 
  • Heavy sweating
  • Muscle cramps
  • Pulse rate: fast and weak
  • Breathing: fast and shallow
  • Nausea or vomiting
  • Fatigue
  • Weakness
  • Headache and/or dizziness 

Heat Stroke:
  • An extremely high body temperature (above 103 degrees)
  • The absence of sweating
  • Rapid pulse 
  • Difficulty breathing 
  • Throbbing headache
  • Strange behavior and/or hallucinations
  • Confusion, agitation and disorientation
  • Unconscious                             

If you recognize that you, or someone else, are showing signs of a heat-related illness, stop the activity immediately, find a cool place to rest, hydrate and seek medical attention if necessary.

Remember, Heat Stroke is a MEDICAL EMERGENCY that can be fatal if not treated promptly.  Call 911 right away if you suspect Heat Stroke.

It’s National Severe Weather Preparedness Week


Bet you did not know that National Severe Weather Preparedness Week is this week, April 22 to April 28. 

I am positive most of you have seen, read, or heard about several very significant severe weather situations that have devastated various parts of the US over the last couple of weeks.  While there was some very tragic, and mostly unavoidable, loss of life during a few of these storms, we also know many more were saved due to the fact they PREPARED for the emergency before it happened.  They knew what to do and how to do it!

We know that severe weather CAN happen here.  Please take a moment to go here, Severe Weather , to learn more.  Also, please watch the below video from FEMA Administrator Craig Fugate.

Preparing for Irene

NOTE: Mr. Lopes, a life long Montgomery County resident, is an emergency management professional and has published numerous articles and information on disaster safety for some 25 years. I am grateful he is sharing his knowledge with all of us.  Bill Delaney, MCFRS

by Rocky Lopes
Emergency Manager and Disaster Preparedness Guy

It's all over the news, Hurricane Irene is making its way up the East Coast.  We haven't had a visit from a tropical system in Montgomery County in quite some time, so it's time to dust off our preparedness plans.

However, we have to be realistic.  We don't live on the ocean here in Montgomery County, so we think that a hurricane won't really affect us like it may affect homes, condos, and other structures on the Atlantic coastline.  If you own property or are visiting this blog from a location on the coast, you should consult your local emergency management (county, city) for information applicable directly to your area of concern.  Here is a link to a list of all emergency management agencies serving Maryland jurisdictions.

Here are some realistic preparation tips for a visit from what we may call a "brush-by" of a tropical system. These preparation tips have been adjusted to apply to an inland area such as Montgomery County.  There are three major issues that we need to be concerned with:
Wind
Rain and localized flooding
Power Outages

Keep Informed

Make sure that you arrange to get storm alerts in real-time.  A  NOAA Weather Radio provides location-specific information in real-time, and will sound an alert for events like floods, tornadoes, high winds, tropical storms, and much more.  You can get one of these radios at any local electronics specialty store.  Also consider signing up for  Alert Montgomery if you haven't already done so. It's a great way to get localized and personalized information from our County's Department of Homeland Security and Emergency Management.

Be aware that tropical systems are variable and may change direction and intensity quickly.  Continue to watch local TV and listen to local radio for updated information.  Also, do NOT pay attention to the projected "center" of the storm.  The storm will affect large areas over hundreds of miles.  Areas where the eye of the storm are not the only places where damage and destruction can happen -- tropical systems can wreak devastation in a path over 400 miles wide.

Get Ready

Discuss with your loved-ones what plans you have made.  If a problem happens like localized flooding from heavy rain, what will you do?  Where will you go if advised to leave for a while?  Choose a family or friend's place that is located on higher ground.  Call them in advance to see if you can come stay with them for a while.  It's always best to have these arrangements made in advance.

Bring things inside that could blow around and cause damage to your or a neighbor's home.  Trash cans, lawn furniture, picnic table umbrellas, outdoor decorations, wind chimes, hanging baskets, and so forth -- anything that could be blown by gusts of winds should be brought indoors, such as into a garage, basement, or shed.  We have to remember that even if we don't get a full-frontal assault of a major hurricane, it's the winds that cause a lot of damage where we live away from the coast.  Get ready for wind.

Be a leader:  advise your neighbors why you are bringing things inside and ask them to do the same.  Do it for elderly, disabled, or neighbors who are out of town who may not be able to take the precautions themselves.

In case the power may go out for a prolonged period of time, take time now to fill voids in your refrigerator and freezer.  That is, fill plastic bags with ice and fill your entire freezer.  Foods will keep frozen longer if there is less empty space in the freezer.  The same is true for the fridge. Rinse out and fill empty plastic bottles with water, and put them in the fridge.  Do it days in advance of the storm so the water can chill.  Turn the fridge to a colder setting, but not so low as to cause things to freeze.

Be realistic when stocking up on perishables. You don't really need five gallons of milk, 10 pounds of butter, and 19 dozen eggs.  Streets may be impassable due to debris in the road or stores may be closed, but only for a relatively short time.  Sure, stock up, but buy things that you and your family ordinarily will consume within a week's time. 

Get out the old-fashioned time-passers to keep kids (and adults) occupied.  Amazing how technology-dependent we all are these days, and kids become agitated if their favorite things to do don't work because the power is out.  Get some good books, and plan to read together as a family if the power is out.  (What a novel idea!)  Also, card games, Parcheesi, Monopoly, or other board games can be a lot of fun, especially because you probably haven't played these games together in a long time. 

It is a good idea to have canned foods and a manual can opener handy.  If the power goes out, you may have to live on canned fish, soup, and vegetables for a while.  A sterno portable stove is useful to heat things like soup in a power outage. 

If you take prescription medications and your supply is low, consider requesting a refill now so you don't run out if roads are blocked by downed tree limbs or flood waters.

Get out the flashlights and abandon the candles. (Candle fires are common during power outages and candles have not been recommended as emergency supplies for decades.)  Make sure you have fresh batteries for flashlights.  Here's a tip:  keep batteries out of flashlights until needed.  When batteries are kept in flashlights, they incur a slow drain and may not last as long.

Also, have a battery-powered radio so you can listen to local news if the power is out. 

Do not anticipate that a smart phone will continue to work or have ongoing service during a storm or a prolonged power outage. However, plan for a battery-charging backup and have a car charger handy.  You can recharge a mobile device from your car if the power is out in your home.

During the Storm
Continue listening to local TV and radio for updated information.

If advised of a Flash Flood Watch or Warning, take heed.  There are many local roadways that become inundated by rainwater.  If you must drive during or after the storm and you come upon a roadway covered with water, think.  Think about those who love you.  How would they feel if you were washed away by quick-moving floodwaters?  As little as a foot of water can sweep a vehicle off the road. And here's a little-known fact:  the tires of SUVs are larger and thus have more buoyancy, so SUVs are more likely to be displaced from a road than a car with smaller tires.  Turn around, don't drown!

Be aware that tornadoes sometimes spin off of a tropical system.  That is: there is a real threat that a tornado could be generated from this storm and affect our area.  If a tornado warning is issued, then grab your radio and flashlight, and move everyone to the lowest level of the building or home that you are in.  Get inside a room without windows -- a bathroom is a good choice.  Wait there until you hear that the warning is lifted and it's safe to come out. 

If power goes out or overhead wires are knocked down, report it to your power company.  It's also a good idea to go around your home and turn off anything that was on when the power went out so there won't be a huge surge (and potential damage) when the power comes back on.  Include air conditioning, televisions, dehumidifiers, and sensitive equipment like computers and electronics.

Use flashlights and non-perishable foods during a power outage.  Try not to open the refrigerator or freezer at all, or if you must, get everything out that you need at once and quickly shut the door.

Only call 9-1-1 or emergency services if there truly is a life-threatening emergency.  Our life-saving protectors will be busy and we need to give them a break so they can respond to the most urgent needs. 

Finally, have phone numbers handy for important contacts -- PEPCO (1-877-737-2662) or your local power company (if different), family, and elderly and disabled neighbors.

Be Patient

One of the most frustrating things after a storm is the waiting.  Use your non-electronic time passers to enjoy the time when you're disconnected.

Check on family, elderly, and disabled neighbors about their safety. 

Be Safe

Storms are one of life's major inconveniences.  But with a little realistic preparation and discussion with your loved-ones, you'll be more confident that you and those you love will be safe.

Tornado Folklore

By: Rocky Lopes

There is this thing called "folklore," which by definition can include legends, oral history, and popular beliefs. Folklore creeps into some of our thinking about severe weather, and may be something you have heard or have passed on to children. Let me share some "Tornado Folklore" that many of us have heard:

Folklore: Tornadoes only happen in "tornado alley" -- roughly defined as states in the Midwest from Texas to Minnesota.

Truths: While many strong tornadoes happen in the Midwest, they can -- and have -- happened in every state.

In many years, more people have died as a result of tornadoes that happen east of the Mississippi River than west of the river. Why? People who live west of the Mississippi River are more accustomed to having tornadoes, and have learned what to do, when to get to shelter, and how to be safe since they were a child.

Folklore: Tornadoes never hit cities.

Truths: Since the majority of land area in the U.S. is unpopulated, it appears as if tornadoes only strike rural areas.  The relative amount of area of a city with tall buildings is small compared with the city as a whole.

Unfortunately, we learned in April and May, 2011, that this belief isn't true. Just ask residents of Tuscaloosa, Alabama, or Joplin, Missouri.

Folklore: You need to open windows in your house to equalize air pressure before a tornado may strike, to prevent the house from exploding.

Truths: Even with windows closed, houses have enough openings to vent the pressure difference in the time it takes a tornado to pass.  Some of the strongest thunderstorms have longer duration of low air pressure -- houses do not explode during those storms, so they won't during a tornado.  Opening windows is a dangerous and useless waste of time, and could actually be harmful to the house.

Folklore: Get into the southwest corner of your basement in case of a tornado.

Truths: Being underground is definitely safer than being above ground, but no particular corner of a basement is safer than any other.  Tornadoes can come from any direction. While it may appear that tornadoes in the Midwest always move from southwest toward to northeast, that is not always true. In fact, recent tornadoes in 2011 came from all directions

Folklore: Tornadoes do not cross bodies of water

Truth: Tornadoes cross rivers regularly. The stream of tornadoes that occurred on April 27, 2011, crossed many rivers in 17 states.

Folklore: Once the tornado has passed, you can go out to inspect for damage.

Truths: Some strong storms can produce more than one tornado, sometimes several tornadoes at a time. On April 27, 2011, 362 tornadoes happened from two long lines of storms, creating the largest tornado outbreak in U.S. history.

Folklore: Our area doesn't have sirens, so we will not get notified in case of a tornado.

Truths: We are fortunate in Montgomery County to have many ways to get warnings in case of tornadoes or other emergencies. 

Sign up for Alert Montgomery. This system will send alert messages to any device you specify: cell and smart phones, email accounts, PDAs, and pagers. It's free, and you can adjust settings on it to receive alerts for life safety, fire, severe weather, accidents involving utilities or roadways, and crime.

NOAA Weather Radio will sound an alert for severe weather and other emergencies that are issued for Montgomery County. Once you set it, it will provide a tone alert with a radio announcement describing what is happening and what to do. You can buy one of these radios from electronics stores.

Providers of cable television service in Montgomery County, e.g., Comcast and FiOS, will broadcast notices from the Emergency Alert System (EAS) when issued by the county. EAS notices are broadcast on all channels simultaneously.

Be sure to "Like" the Facebook page for the Montgomery County Fire and Rescue Services (MCFRS) Department, and Montgomery County Department of Homeland Security.

And follow MCFRS on Twitter.

Severe Storms

With the tragic events in Joplin, MO yesterday and our forecast for today, I thought it a good time to provide all of you some safety tips as well as a resource for now and in the future.

When a tornado warning is issued for your area:

• Seek shelter in a windowless interior room in the lowest level of the house. Go to the basement, if you have one. Stay away from windows.

• If you are caught in the open during a tornado, stay low and go to a drainage ditch or other low point on the ground. 

• If you are in your vehicle during a tornado, get out of the vehicle and go to a drainage ditch or other low point on the ground.  Do not try to outrun a tornado.

To prepare for a severe weather event, please go here: Severe Storms

A great resource from Weather.com: Severe Weather: Track the Storms

As always, be safe and be prepared!

Turn Around - Don’t Drown!

Many Roads in Montgomery County Susceptible to Flooding so Consider Alternate Routes Beforehand!

County residents are urged to be alert to changing weather conditions and should be prepared for possible flash flooding over the next 24 hours as a storm system moves into the area and is expected to bring heavy rains.
  
When it rains heavily, there may be flash floods, flood warnings and flood watches issued.  Flash floods more often occur in mountain streams, hilly areas or low-lying areas.  But they do happen in urban and suburban areas like Montgomery County, as well.  Flash floods can occur even though it's not raining where you are.  It may be raining hard farther upstream and raining so hard that the water can not be absorbed into the ground.
  
Safety Tips:
If a flash flood warning is issued, act immediately.  Don't wait for high water to dictate your course of action.
Know your location when you are driving.  If you needed rescue, would you be able to direct emergency crews to your location?  Distracted driving can lead to a situation where you are stranded and unable to direct emergency crews to you.  Be alert!
  
Never drive through a flooded road or bridge.  Turn Around - Don’t Drown and try an alternate route!  In many cases, it takes far less than a foot of water to incapacitate a vehicle.  It may stall, leaving you stranded, and depending on the level of water, you may not be able to open a vehicle door.  Do not underestimate the power of moving water.
  
Watch for flooding at bridges and dips in the road.  Never drive where water is over bridges or roads. Turn around - Don’t Drown!  The bridges or the road could suddenly be washed out. If you're driving at night be especially careful.  Often visibility is limited due to wind and rain.
  
Often what you can't see below the surface of the water is far more dangerous than the high levels of that water.  Remember that rocks, tree limbs and other debris can be caught in moving water and can be dangerous if you are forced to walk, wade or swim through flood waters.
  
If you have to walk or wade through flood water, use a stick to poke the ground in front of you with each step.  It can help you determine water levels, the bottom surface and the safest possible way to get to higher ground.
  
Remember that flash floods can come without warning, and sometimes without weather.  Be alert and heed all warnings and recommendations from officials. From FEMA's website, some further information about driving through flooded roadways:
  • Six inches of water will reach the bottom of most passenger cars causing loss of control and possible stalling.
  • A foot of water will float many vehicles.  
  • Two feet of rushing water can carry away most vehicles including sport utility vehicles (SUV's) and pick-ups
TURN AROUND - DON’T DROWN and try an alternate route!
