Black Hills heat wave gives way to severe weather
RAPID CITY, S.D. (AP) — The Black Hills area of South Dakota broke out of a weeklong heat wave with some severe weather.
Rain and hail — some baseball-sized — pounded the area Friday afternoon and a tornado touched down briefly near Hermosa, the Rapid City Journal reported (http://bit.ly/1dBif8h ).
The twister appeared in an open area about six miles southwest of Folsom, where it didn't have the opportunity to do much damage, National Weather Service meteorologist Susan Sanders said.
"It doesn't look like it caused any damage," Sanders, in the Rapid City office, said. "It just lasted a minute or two."
At least one piece of hail near Hisega was the size of a baseball — 2.75 inches in diameter.
Melissa Smith, a National Weather Service meteorologist and hydrologist, said an inch of rain fell in Rapid City within 45 minutes Friday afternoon.
"The water was up to the curbs on the major streets," Smith said.
The deluge prompted the Weather Service to issue a series of flood and flash flood advisories for parts of Pennington and Meade counties, and sirens in Rapid City announced the flash flood warning.
Rapid Creek near the fairgrounds overflowed its banks.
Minor flooding also occurred in downtown Rapid City, Black Hawk, Box Elder, Caputa, Ellsworth Air Force Base, Hayward, Keystone, Rapid Valley, Rockerville and at the Rapid City Regional Airport.
