     Severe weather, heavy rain and flooding impacted nearly every corner of Illinois in 2010. Tornadoes touched down 48 times, injuring 40 people, killing one person, and causing hundreds of millions of dollain damage. 


    Heavy rainfall the past three years has resulted in 10 fatalities in Illinois, eight of them in automobiles caught in flood waters. The bottom line: Illinoisans must be prepared for the impacts of severe thunderstorms, tornadoes and flooding.

     To help the citizens of Illinois be more aware of the dangers of severe storms and flooding, the National Weather Service (NWS), in cooperation with the Illinois Emergency Management Agency (IEMA), has declared the week of February 27 – March 5, 2011 Severe Weather Preparedness Week in the state of Illinois.




Preparedness Saves Lives

There is nothing we can do to stop severe thunderstorms, lightning, tornadoes or floods from developing. However, there are things that everyone can do to minimize the impacts of severe weather on our lives.


What you can do to be prepared:  

    This can be done by monitoring a weather alert radio, local radio & TV broadcasts, NWS web pages, or various applications on computers and smart phones. 

    DON'T just rely on one method - especially storm sirens - which are NOT designed to be heard indoors by everyone.  

    Do this for your home, business, schools and when you are traveling. Designate places to go to seek safe shelter from a tornado or severe thunderstorm. Pick two places to meet in case you are separated from your family or co-workers. 

    While traveling or when away from home, know the names of the locations you are visiting - especially county and city names.  

    Learn how to use a fire extinguisher, how to administer CPR, and how to turn off the electricity, gas and water supplies in your home. 

    Inspect your home for potential hazards such as weakened trees or limbs, cracked windows or worn roofing. 

    When  you build a new structure - or renovate an existing one - there are ways to prevent wind damage to roofs, upper floors and garages. Rafters, trusses, walls and doors can all be reinforced.  

    Some storms produce power outages that will last for several days. Having the following items will help you cope with the disaster:
    • Bottled water
    • Non-perishable food
    • Flashlights & extra batteries
    • Extra clothing & blankets
    • An extra set of keys & cash
    • Medications & a first aid kit
    • Personal hygiene items
    • Pet supplies
    • A weather alert radio or portable AM/FM radio



"By failing to prepare you are preparing to fail."
