Heavy rain and slow-moving storms bring flash flood warnings to southwestern Minnesota and northwestern Iowa

A slow-moving storm system is delivering heavy rainfall and thunderstorms across southwestern Minnesota and northwestern Iowa through Sunday evening. Rainfall rates of 1 to 3 inches per hour are possible, with localized totals reaching 3 to 5 inches in some areas. Some regions have already received 2 to 4 inches of rain in a short period, leading to flash flood warnings and a flood watch in effect for parts of southwestern Minnesota and northwestern Iowa. The storms are expected to weaken after sunset, though isolated showers and thunderstorms may return overnight. A second weather system is forecast to arrive Monday night into Tuesday, bringing more rain to northern Minnesota and central Minnesota. Conditions are expected to be quieter and drier later in the week. In the Des Moines metro area, heavy rain has caused flooded roadways and several temporary road closures. Officials advise drivers to avoid flooded roads and use caution if travel is necessary.
