(Columbia) -- Thousands of South Carolinians have no electricity this morning following this week's ice storm.

South Carolina Electric and Gas Company says about 150,000 customers have no power this morning. Spokesman Robin
Montgomery says most of those without electricity are in the Columbia area. SCE&G serves the Midlands and Lowcountry.

Montgomery says it's too early to determine how long it will take to restore service.

Progress Energy reports about 63,000 customers without electricity in the Pee Dee.

Duke Power says in the Upstate, most of the power outages have been in the Anderson and Greenville areas. Crews are working to get the lights back on all over the state. Duke reports 9,300 customers were without power early Tuesday morning.

The Transportation Department continues to work to clear South Carolina roads. Spokesman Pete Poore says more than 900 workers are
trying to keep the roads clear. Poore says the agency has used nearly seven thousand tons of sand, nearly six thousand tons of
salt and thousands of gallons of calcium chloride and salt brine on the roads.

The National Weather Service has canceled winter weather warnings and advisories for most of South Carolina. A winter
weather advisory remains in effect in the mountains and foothills until noon.

Governor Mark Sanford has delayed the opening of state offices until noon in 37 of the state's 46 counties. Offices will open on
