Flash flood watch issued for most of Iowa

DES MOINES (AP) — A flash flood watch has been issued for much of Iowa as the remnants of Tropical Storm Cristobal move north and collide with another storm system in the state.

The National Weather Service issued the flash flood watch for Tuesday until midnight. As much as 4 inches of rain could fall in places, especially in central Iowa, the weather service said. That could send some already-swollen creeks and tributaries out of their banks.
