A strong spring storm will continue to produce widespread rain across northwest Iowa and northeast Nebraska this morning. The heaviest rains will fall south of a Vermillion South Dakota to Sioux Rapids Iowa line, where an additional 1 to 2 inches of rain will fall this morning. This could cause flash flooding due to the already saturated grounds. A FLASH FLOOD WATCH is in effect until 1 pm CDT for those areas including the Sioux City metro area. The heavy rains will taper off by afternoon and will help alleviate the flash flood threat during the afternoon. A Flash Flood Watch means that conditions may develop that lead to flash flooding.
