A deadly winter storm has covered much of the southeastern United States with heavy snow, freezing rain and ice.
The storm swept from Texas to the Carolinas, causing hundreds of thousands of power outages Wednesday and closing businesses and schools. Thousands of flights were canceled, most of them in Atlanta.
Some areas in North Carolina reported more than 25 centimeters of snow. Meteorologists say more than a centimeter of ice from the storm is weighing down and breaking tree limbs, and snapping power lines knocking out power.
The National Weather Service called the storm "an event of historical proportions." Authorities say the wintry mix has caused two deaths in Mississippi and at least three in northern Texas.
The storm is expected to move north, up the eastern U.S. coast, Wednesday and Thursday.
Businesses, schools and even the federal government is expected to close as weather conditions worsen. The White House announced Wednesday it has postponed a public event scheduled there tomorrow due to weather conditions.
White House spokesman Jay Carney says the Federal Emergency Management Agency has dispatched crews across the southeast and has activated crews in the Washington region.
