Snow, sleet and freezing rain have hit the eastern two-thirds of the country, stretching from the southern Rockies to New England, with some regions bracing for the worst ice storm in more than a decade.
Flights cancelled, power outages spread: According to FlightAware, more than 13,000 flights scheduled for Saturday and Sunday have been cancelled, including widespread disruptions at major hubs such as Dallas–Fort Worth, Chicago, Atlanta and Washington. Power outages climbed past 160,000 late Saturday, mostly in Louisiana and Texas, as ice-laden trees and downed power lines caused damage comparable to hurricane impacts in some areas.
