The counties of Kossuth, Winnebago, Worth, Wright, Hancock, Palo Alto, and Franklin in Iowa are under a Flash Flood Watch until 7 am on Wednesday morning.
Widespread moderate to heavy rainfall is expected across much of central Iowa from later today through tonight. Repeated rounds of rainfall, especially from around this evening into early tonight,
may lead to rapid heavy rainfall accumulations and flash flooding. Many areas are already saturated from rains over the last week, increasing the threat of flash flooding.
