Hail, snow, a tornado and a tropical storm made it a "severe weather" Mother's Day in much of the center of the United States and on the Carolina coast on Sunday.

Tropical Storm Ana, the first named storm of the 2015 Atlantic hurricane season, weakened after making landfall near Myrtle Beach, South Carolina, but high surf and flooding still threatened the coast.

In eastern South Dakota, a tornado touched down at 10:50 a.m. (1550 GMT) in the town of Delmont, population 234, demolishing a Lutheran Church and damaging homes. No injuries or deaths were reported but emergency workers were dispatched, said Philip Schumacher, meteorologist with the National Weather Service.
