Rain continues to train over the US Hwy 20 corridor from Waterloo to Dubuque. Numerous flash flood warnings are in effect (some of which weren’t blogged due to an enternal issue.) More thunderstorms are beginning to develop to the south of US Hwy 20 near the US Hwy 30 and Interstate 80 corridors. Heavy rain and flash flooding are possible with these new storms along with the current activity to the north. Any updates will be on the Twitter feeds of NWS offices to the right.
