South Carolina insurance companies say a weekend hailstorm caused about $45 million in property damage. Insurance News Service executive director Russ Dubinsky said Monday that companies reported more than 18,000 claims had been filed. He said the number could go up as people discover more damage. State Farm spokesman Roszell Gadson says people with unrepaired damage should protect property from storms forecast for overnight Monday into Tuesday morning. Gadson says roofs should be covered with tarps to prevent further water damage.
