Flood watches were in effect in the U.S. southeast early Monday as forecasters warn of the possibility of torrential downpours on Labor Day across already saturated ground.
Waves of showers and storms were expected to develop Monday in the region, as moisture from the Gulf of Mexico continues to stream across the South, the National Weather Service said. Some training storms — storms that drop several inches of rain as they move over the same areas like train cars — were also possible, the weather service said.
