Wed-Fri, April 17-19th Heavy Rain/Flood Event Update #3

(12:30PM - 4/18/19) Periods of rain and isolated t'storms, with flooding potential, will continue through Friday evening for portions of the state...

Periods of rain and t'storms pushed across much of the state last night and this morning. There were a few corridors in Central and Southern Illinois that received 1-2" of rain, though most locations across the state picked up less that 1"

Additional periods of rain and isolated t'storms are likely to continue to be possible across the state through Friday evening. Rain will end across Northern and West-Central Illinois tonight, with final rainfall amounts ending up light and no flood potential. However, further south across Eastern and Southern Illinois, periods of rain and isolated t'storms will continue to be likely through Friday evening. Widespread rainfall totals across much of Eastern and Southern Illinois will be in excess of 1", with totals of 2-4" likely in some areas...most likely across portions of Southeast Illinois. A low to moderate flood threat will be possible for these areas, given the wet pattern that has been in place for over a month now and the expected heavy rainfall totals.

Below is our updated TAM flood forecast for this event.
