As some S.C. communities were cleaning up Wednesday from damage from tornadoes and strong winds, other areas in the Palmetto State contended with flooding that closed numerous roads.

Heavy rains from Tropical Storm Frances caused significant flooding in parts of the Upstate and Pee Dee, state and local officials said.

In Oconee County, for example, flash floods forced the closing of 30 roads, said Henry Gordon, director of the county emergency agency. Most just had standing water, but in four cases the roadbeds were washed out, he said. One mobile home was swept off its foundation.

Flooding in Chesterfield County closed 17 roads, said Joe Farmer, spokesman for the state Emergency Management Division. He said his office didn’t have any reports of injuries.

Several S.C. rivers reached flood stage Wednesday.

In Richland County, the Congaree River near the Carolina Eastman plant was expected to crest this afternoon 6 feet above flood stage, said Bernie Palmer, chief meteorologist at the National Weather Service’s Columbia office.

There are no homes in that immediate area, and the plant is some distance from the river.

A flood warning also was issued Wednesday for part of the Broad River in the Blair area in Fairfield County.

The Broad River near Blacksburg in Cherokee County was expected to crest Wednesday night about 8 feet above flood stage. At that level, several structures along the river would be flooded, according to the National Weather Service.

Rains brought by Frances were particularly heavy in the Upstate: 9.75 inches in Walhalla; 9.5 inches in Pickens County; and 9 inches in Greenville, Farmer said.

In the Columbia area, the highest recorded total rainfall over the past two days was 3.45 inches at Owens Field, according to the National Weather Service.

Fortunately, the state should begin drying out as Frances moves north, Palmer said.

“We’ll dry out. It’s just a matter of time.”

The National Weather Service forecast for the Columbia area through Friday calls for a 20 percent chance of storms.

The National Weather Service confirmed at least 12 tornadoes spawned by Frances in eight counties Tuesday. Total damage estimates were not available Wednesday; Farmer said he won’t know whether the state will request federal disaster assistance until his office receives completed damage reports from the affected counties.

Based on preliminary reports, the counties hardest hit by wind or rain were Oconee, Chesterfield, Darlington, Marlboro and Sumter, Farmer said.

Officials in Sumter County, where two tornadoes hit south of Sumter, initially reported nearly $2 million in damages. Updated figures were unavailable Wednesday.

In Richland County, where tornadoes struck the Fort Jackson and Gadsden areas, total damage was estimated at $250,000. But county emergency services spokesman George Rice said Wednesday the figure does not include damage at Fort Jackson and likely will be higher after private insurance claims are submitted.

Kershaw County suffered nearly $500,000 in damage from tornadoes, mainly in the Cassatt area, said assistant county administrator Brenda Wilhite. Assessment teams counted 38 damaged properties lying mainly between Providence and Lockhart roads, north of Camden, she said.

Two twisters ran parallel along Providence Road through Cassatt. A third storm hit Mill Creek Road near the Lancaster County line.
