Factbox - Over 200,000 U.S. customers without power after Hurricane Michael

(Reuters) - More than 200,000 homes and businesses in the U.S. Southeast were still without power on Monday after Hurricane Michael swept up the East Coast from Florida last week, according to local power companies.

In total, Michael caused over 3 million outages from Florida to New York after hitting the Florida Panhandle as a Category 4 storm with maximum sustained winds of 155 miles per hour (250 kph).

Some customers in the hardest-hit parts of Florida may have to wait another week or two until their power is restored, local utilities said.

The Florida Division of Emergency Management said on its Twitter site that about 150,000 homes and businesses in the state were still without power, including more than 90 percent of customers in Calhoun and Gulf counties and over 80 percent in Jackson and Liberty counties on the Panhandle.

Southern Co's Gulf Power unit estimated it would restore power in the hardest-hit areas, like Panama City, by Oct. 24, according to the company website.
