Tornado Season Preparedness

Almost two-thirds of tornados in Illinois occur during the months of March, April and May - and approximately half occur between 3 and 7 p.m.  All members of the family should be taught to recognize the danger signs and a basement room or windowless, interior room should be designated as the tornado shelter area.  

To give advance warning that a tornado has been spotted or is heading toward Glen Ellyn, the Village has outdoor severe weather warning sirens positioned strategically throughout the community.  These sirens are sounded if the National Weather Service issues a tornado warning for DuPage County, or if a storm or tornado poses a threat to Glen Ellyn.  The sirens are tested every first Tuesday of the month at 10 a.m.  In addition, residents are encouraged to purchase a NOAA Weather Radio, the best source for comprehensive weather and emergency data from the National Weather Service, broadcasting 24 hours a day.
Heavy Storm Preparedness
Most of Glen Ellyn's flooding and drainage problems occur during and after heavy storms. Storms can happen at any time, but especially in spring and summer. Floods can happen fast, so here are some suggestions to prepare:
  • Keep storm sewer inlets and drainage ditches clear of debris, including leaves and grass clippings.
  • Make sure your sump pump is working.
  • Monitor potential flood hazards on All Hazards NOAA Weather Radio, local radio, television or on the internet at
  • Copy your most important papers (mortgage papers, deeds, passport, bank and credit card information).  Keep the copies in your home and place the originals outside your home in a secure place like a safety deposit box.
  • Go through your basement (if not your entire house) and take photos of your most valuable possessions (furniture, musical instruments and electronic equipment).  Save receipts for any expensive household items, such as appliances and electronics, to have proof of their cost.

Heat Wave Preparedness

Residents are encouraged to prepare for hot weather.  Follow these tips to protect yourself:
  • Stay indoors and refrain from strenuous work during the hottest part of the day.
  • Stay hydrated. 
  • Drink plenty of water.
  • Keep in mind that consuming alcohol and caffeinated drinks can cause you to become dehydrated.
  • Check on family, friends, and neighbors who do not have air conditioning or who spend much of their time alone.
  • Never leave children or pets alone in closed vehicles.
  • Take frequent breaks if you must work outdoors.
  • If your home does not have air conditioning, go to a public building with air conditioning each day for several hours.
  • Familiarize yourself with these terms pertaining to heat emergencies:
  • Excessive Heat WATCH means conditions are favorable for an event to meet or exceed local excessive heat warning criteria in the next 12 to 48 hours.
  • Excessive Heat WARNING means that heat values are forecast to meet or exceed locally defined warning criteria for at least two days.
  • Excessive Heat ADVISORY means hazardous heat conditions have begun or will begin within 36 hours and, if caution is not exercised, they could become life threatening.
  • The Village is prepared to provide temporary escape from the extreme heat should the need arise.  There will be a room designated for this purpose at the Civic Center located at 535 Duane Street, Glen Ellyn.  The below link will provide additional useful information to assist you in preparing for these conditions.
