...Severe Thunderstorm Safety...

Severe thunderstorms pose a threat to life and property. They
produce damaging downburst winds of around 60 mph or greater, and or
large destructive hail, one inch in diameter or greater. Flooding
rains, frequent cloud to ground lightning, and tornadoes are also
possible in severe thunderstorms.

A severe thunderstorm watch means severe thunderstorms are possible
in the next few hours and to be prepared.

A severe thunderstorm warning means a thunderstorm capable of
causing damage and injury has been sighted or detected by radar. Go
indoors and stay away from windows. Heading into the basement or the
lower level is encouraged as some storms have winds as strong as
tornadoes and some can intensify rapidly and produce a tornado.

On August 2nd 2015, severe thunderstorms moved across northeast
Illinois and produced a swath of large hail and wind damage from
Dekalb to Evanston. One person was killed and three were injured
seriously from wind damage with these storms. When thunder roars, go
indoors.
