South Carolina Electric & Gas Company had about 60 customers without power Monday afternoon. Duke Energy reports about 70 outages.

Forecasters are trying to determine if it was a tornado that damaged about a half-dozen houses and forced the closure of about four miles of Maybank Highway on Wadmalaw Island for a time Sunday just south of Charleston.

The National Weather Service and local emergency officials say the damage was minor and no injuries were reported.

The storms stranded a dozen boaters and campers in the Lowcountry who had to be rescued by state and local officials.
