The US East Coast was hit by a major winter storm yesterday, pummeling the region with high winds, rain, and snow and flooding coastal areas. At least six people have died as a result of the storm, according to The Washington Post.

This is the second major storm to hit the region thus far this year. This week’s nor’easter that formed over the last week was particularly bad, with an area of low pressure holding the storm over the New England coast, resulting in widespread coastal flooding. That flooding was helped by the tides brought by a nearly-full moon, adding an additional couple of feet to the water line at high tide.

The storm had other effects up and down the East Coast as well: airlines canceled thousands of flights, and Amtrak suspended train service between Washington DC and New York City overnight — service has since been restored. High winds from the storm snapped powerlines, leaving more than two million people without power in the region, according to The New York Times. The storm has killed at least six people in New York, Virginia, Maryland, and Rhode Island, all as a result of falling trees and branches.

The National Weather Service for Boston warned of continued flooding through the afternoon, with a surge of two and a half to three feet, and 20 foot swells at sea. Twitter users took pictures and video of the flooding in Boston.

The National Weather Service says that flood warnings will remain in effect in Massachusetts until Sunday morning, when the storm is expected to move on.
