DES MOINES, Iowa (AP) — Another round of heavy rain could develop Monday night generating renewed concerns of flash flooding in the southern half of the state. The National Weather Service in Des Moines says many of the same areas that received heavy rain Sunday could be in the bullseye for another round Monday. A flash flood watch was in effect through Tuesday morning for a large portion of central and south-central Iowa.

Weather service forecaster says thunderstorms with heavy rain are expected between 9 p.m. Monday and 4 a.m. Tuesday. Rainfall rates of 1 to 3 inches per hour may be common with localized totals of 5 inches possible. With soil already saturated flash flooding could quickly develop. Some storms south of U.S. Highway 34 could produce hail and damaging wind.
