Severe Weather

Weather Radios
To get the most up to date weather information, residents are urged to obtain and use a National Oceanic and Atmospheric Administration (NOAA) Weather Radio. NOAA Weather Radio All Hazards (NWR) is a nationwide network of radio stations broadcasting continuous weather information directly from the nearest National Weather Service office. NWR broadcasts official Weather Service warnings, watches, forecasts and other hazard information 24 hours a day, 7 days a week. NWR also broadcasts warning and post-event information for all types of hazards including: natural (i.e. earthquakes or avalanches), environmental (i.e. chemical releases or oil spills), and public safety (i.e. AMBER alerts or 911 telephone outages). NOAA emergency alert weather radios activate to provide immediate information about life-threatening events, giving extra time to prepare and evacuate, if necessary. Radios can be tuned to provide the listener with area specific information. NOAA weather radios can be purchased at retail stores and/or online.

Severe Summer Weather
The term “tornado watch” means that weather conditions are right for the formation of a tornado. Residents should listen to local radio and television stations for weather information during a tornado watch, even if the sky is blue. The term “tornado warning” means that a tornado has been spotted.

Pay attention to where it was seen, the direction of travel, and the time period the warning lasts. Take cover immediately if in the path of travel. If its path covers Warrenville, the outdoor warning sirens will sound for three minutes with a steady tone. Radio and TV stations will also provide warning information. Seek shelter inside (in a storm cellar or reinforced building if possible) and stay away from windows. Take a flashlight, radio or TV and listen for updates on the storm’s activities.

What to do During a Tornado

In a home, the basement offers the greatest safety. Seek shelter under sturdy furniture or stairway or in the center of the house on the lowest floor, in a small room such as a closet or bathroom. Stay away from windows; if they are open leave them alone. Do not go to the southwest corner of the basement of the building. In an office building, go to an interior hallway on the lowest floor or to the designated shelter area of the building. In a school, follow advance plans and go to an interior hallway on the lowest floor. If the building is not of reinforced construction, go to a nearby building that is, or take cover outside on low, protected ground. Stay out of auditoriums, gymnasiums and other structures with wide, free roof spans. In a shopping center, go to a designated shelter area (not a vehicle). In open country or when camping, move away from the tornado’s path at right angles. If there is no time to escape, lie flat in the nearest ditch or ravine. Stay out from under large trees, branches and high power lines. Many campgrounds have designated shelter areas; be aware of their locations prior to severe storms.

Lightning and Thunderstorms (Lightening safety brochure - PDF)

Tornadoes are not the only dangerous summer weather. 

Thunderstorms and the accompanying lightning can also be very dangerous. According to the National Weather Service, lightning is one of the leading causes of weather-related deaths in the United States. NO PLACE outside is safe when thunderstorms are in the area! If you hear thunder, lightning is close enough to strike you. When you hear thunder, immediately move to safe shelter. Safe shelter includes either a substantial building with electricity or plumbing, or an enclosed, metal-topped vehicle with windows up.  Stay in safe shelter at least 30 minutes after you hear the last sound of thunder.

Once you are indoors, avoid sources of electricity. Stay off corded phones, computers, and other electrical equipment that puts you in direct contact with electricity. Avoid plumbing, including sinks, baths and faucets, because water is a great conductor of electricity.  Stay away from windows and doors, and stay off porches. Do not lie on concrete floors, and do not lean against concrete walls. Many concrete walls and floors contain metal reinforcement, and this metal may conduct electricity.

If you are caught outside with no safe shelter anywhere nearby, the following actions may reduce your risk:

Get Low! Immediately get off elevated areas such as hills, mountain ridges or peaks.

Make yourself as small as possible! Crouch down, with both feet on the ground. Never lie flat on the ground or shelter under an isolated tree.

Immediately get out and away from ponds, lakes and other bodies of water.

After you have reached shelter, seek information about the storm and the forecast via NOAA weather radio, local radio or TV stations, the Internet, a smart phone app, or other means.

Severe Winter Weather
Before a winter storm or the extreme cold hits, do the following:
  • Gather emergency supplies for work and/or home
  • Winterize the home
  • Protect water pipes
  • Prepare for isolation in the home
  • Prepare the vehicle for the winter

During a winter storm and extreme cold do the following:
  • Stay indoors as much as possible.
  • Remember to check on the elderly / homebound
  • When using alternative heat from a fireplace, stove heater, etc., ensure proper ventilation.
  • Eat to supply heat to the body, and drink to avoid dehydration.
  • When outside, dress in layers, and avoid overexertion.
  • Watch for signs of frostbite and hypothermia.
  • Do not travel. If a trip cannot be delayed, consider using public transportation.
  • While in using a vehicle, travel during daylight hours and don't travel alone.
  • Carry a winter storm survival kit, which should contain a blankets / sleeping bag, flashlight (with extra batteries), first aid kit, knife, high calorie, nonperishable foods, extra clothing to keep dry, large empty can and plastic cover with tissues and paper towels for sanitary purposes, smaller can and waterproof matches to melt snow for drinking water, sack of sand or cat litter, shovel, windshield scraper and brush, tool kit, tow rope, booster cables, water container, compass and road map.

The high cost of heating a home may have people searching for alternate, less expensive heating sources. The use of space heaters, wood burning stoves, and fire places are all acceptable alternatives; however, they are all major contributing factors in residential fires, many of which could be prevented by following these few fire safety tips.

Wood Stoves & Fireplaces
  • Have the chimney inspected yearly.
  • Do not use flammable liquids to start or accelerate any fire.
  • Keep a glass or metal screen in front of fireplace openings.
  • Never burn charcoal indoors; it can give off lethal amounts of carbon monoxide.
  • Keep flammable materials away from the mantel.
  • Never close the damper with hot ashes in the fireplace. Be sure the fire is completely out before going to bed.

Kerosene Heaters
  • Be sure it is in good working condition with an emergency shut-off valve in case it is accidentally knocked over.
  • Be sure the room is properly vented. Burning fuel (i.e. kerosene, coal or propane) produces deadly fumes.
  • Never fill the heater while it is operating or hot. Avoid overfilling as cold fuel may expand in the tank when it warms up.
  • Refueling should be done outdoors.

Furnace Heating

  • Have the furnace inspected to ensure that it and all of its controls and emergency shut off are in good working condition.
  • Repairs should be made only by a qualified specialist.
  • If the walls and ceiling near the furnace and along the chimney line are hot or discolored, more insulation or clearance may be needed.
  • Check to be sure the flue pipes and pipe seams are well supported and free of holes and cracks.
  • Make sure the chimney is solid with no cracks or loose bricks.
  • Keep trash and combustibles away from the heating system.

Warming Centers
In a statewide effort to assist Illinois residents in keeping home heating costs down, the State of Illinois has opened warming centers. These centers are open during regular daytime business hours, which may vary from facility to facility. For more information on warming centers, State of Illinois assistance programs, donation centers, cold weather health and "how to's" during the extreme winter months, visit the State's Keep Warm Illinois website.
