Massive Power Outages in Northeast Due to Storms

But flights returning to normal

Utility crews on Thursday worked to restore power to hundreds of thousands of homes and businesses in the U.S. Northeast after a snow and ice storm slammed the region. But flights began returning to normal after thousands of delays or cancellations.

The latest in a series of winter blasts dumped up to about a foot (30 cm) of snow on Wednesday and early Thursday on the Eastern Seaboard from Maryland to Maine. About 100 million people - or one-third of the U.S. population, lives in the region.

The storm coated roads with ice and broke tree limbs, knocking down power lines. At least four deaths were related to the storm, authorities said.
