…FLOOD SAFETY…

The most dangerous type of flooding is FLASH FLOODING. Most smart phones will AUTOMATICALLY receive Flash Flood Warnings from the NWS for the area you are in - even if you are travelling.
NEVER attempt to DRIVE on a flooded road - ESPECIALLY if the
water is flowing
Flash floods can develop in urban areas as well as rural locations
Flash floods typically form when excessive amounts of rain occur in a short period of time - usually an average of 1.00 to 2.00" of rain or more in less than 2 hours, depending on how moist the ground is.
Flash floods are more frequent at night in Illinois, when it is especially hard to judge the depth of the water
Flooding has been a factor in 50 deaths across Illinois since 1995, including one already in 2018. This is more than the number of people killed by tornadoes during the same period.
