The National Weather Service has northeast Illinois under a Flash Flood Watch today. Remnant moisture from Tropical Storm Erin feeding into strong southwest flow forced aloft over a warm front continues to produce a parade of showers and thunderstorms across northern Illinois.
"Training" storms developing and moving repeatedly over the same area gave rainfall totals of 1-3" or more Sunday, and similar action is expected today over much of the Chicago metro area. Two-day rainfall totals could exceed 5 inches in some locations.
Small stream, street/road and basement flooding are the most immediate problems anticipated, but already swollen larger streams and rivers could flood out of their banks in the coming days as the runoff quickly feeds into the hydrologic system.
Elsewhere around the nation, response to major flooding from 10-15" downpours was ongoing in Oklahoma, La Crescent, Minn., and La Crosse, Wis.
