Ready Illinois: Storm Preparedness

Storms develop quickly and can occur with little to no warning. Heavy winds and lightning caused by storms can cause extended power outages, uprooted trees, landslides, and downed or broken utility lines. Additionally, heavy rains can cause flash floods.

Familiarize yourself with the following terms to stay alert and prepared.

• Tornado Watch - conditions are favorable for the development of tornadoes.
  
  
• Tornado Warning - a tornado has been reported by spotters, or National Weather Service (NWS) meteorologists have determined that one is about to form in the next several minutes. Go to a substantial shelter immediately.
  
  
• Severe Thunderstorm Watch - conditions are favorable for the development of severe thunderstorms containing large hail and damaging wind.
  
  
• Severe Thunderstorm Warning - large hail and/or damaging wind has been reported by spotters, or is about to develop. Go to a substantial shelter immediately.

During the storm

• Avoid handling metal, electrical equipment, telephones, bathtubs, water faucets, and sinks, because electric current from lightning can travel through wires and pipes.
• If you are outside, take cover in a stable facility. Avoid taking shelter under trees.
• Tune in to local TV/radio channels for emergency advisories and instructions.
• Avoid walking through water that has seeped into your home; it may contain hazardous materials.
• If you are asked to evacuate your home, follow instructions given to you by emergency personnel.
• Call your local public works department or village hall to report fallen trees or tree limbs, or clogged catch basins.
• Call your local public works department or village hall to report flooded streets.
• Avoid downed power lines and broken gas lines. Report them to 9-1-1.

After the storm

• Assess your immediate environment.
• Report fallen trees, flooded streets, or damaged public utilities to the proper department.
• Stay tuned to local weather stations for updated information.
