FACTBOX-Over 400,000 customers without power in Carolinas after Florence

Sept 17 (Reuters) - More than 400,000 homes and businesses in the U.S. Southeast, mostly in North Carolina and South Carolina, were still without power on Monday after storm Florence hit over the weekend, power companies said. That was down from a total of 1.8 million customers who had power outages since the storm made landfall on Friday. Florence weakened to a post-tropical cyclone on Monday, continuing to produce heavy rain over parts of the Mid-Atlantic region, the U.S. National Hurricane Center (NHC) said in its latest advisory. Duke Energy Corp, the biggest utility in the area with over 4 million customers, has already restored more than 1.1 million of its roughly 1.4 million customers affected by the storm but said total power restoration could take weeks.

Duke said it had more than 20,000 personnel ready to start fixing outages as soon as conditions allowed, including over 8,000 from Duke's Carolinas utilities, 1,700 from the Midwest, 1,200 from Florida and 9,400 from other utilities.

The following lists major outages according to the utilities' websites:
