Rainfall rates of 1 to 2 inches an hour are possible at times.

As a result, areas of urban and poor drainage flooding are likely, with flash flooding possible, including of faster responding small creeks and streams.

Flash flooding can be expected in locations that experience successive thunderstorms moving through. With large portions of the Tri-State having received 2 to 5 inches of rainfall over the past two weeks, almost the entire area is vulnerable to flash flooding. This is especially true for small creeks and streams that are already running at above normal levels for this time of year.
