Flash Flooding Possible This Evening

Ample moisture will stream into the state today ahead of an approaching system. Thunderstorms are expected with this system
today into tonight as it passes through central Iowa. Given the available moisture, very heavy rainfall is expected with the storms as they pass through the state with rainfall rates of 2-3 inches per hour. In addition, the training of storms will also be possible where a series of storms pass over the same location.

Although conditions are still relatively dry in the watch area, the intense rainfall rates may lead to flash flooding, especially in urban areas and low lying areas. A flash flood watch will be in effect from 1pm Wednesday through late Wednesday evening.

Excessive rainfall may result in flooding of low-lying or poor drainage areas, creeks and streams, as well as urban areas. In addition to the flash flood hazard, rising river levels are also possible.

A Flash Flood Watch means that conditions may develop that lead to flash flooding. Flash flooding is a very dangerous situation. You should monitor later forecasts and be prepared to take action should flash flood warnings be issued.
