Last Night’s Rain Totals: Batavia Got 1.56 Inches, Causing Flash Floods

For the fifth time in the past week, a portion of our area had heavy rain, this time late last night/early this morning on the immediate north side of Chicago

According to the National Weather Service Chicago, flash flooding resulted from 1.5 inches to 2.5 inches in two to three hours.

In Kane County, Batavia led the way with 1.56 inches.

The good news is that the tropical air mass that is atypical for October and caused these heavy rain events is departing.

Fast Facts
