Photos: The eastern US is frozen over, with colder temperatures on the way

As cities across the northeastern US dig out from heavy snow, temperatures are plunging to 20 to 30 degrees below the average, thanks to the polar vortex. With the wind chill, it can feel more like -10°F (about -23 °C) in some areas.

Fueled by frigid arctic air and powerful winds, this week’s “bomb cyclone” brought more than a foot of snow in parts of New York City. Around New England, snow accumulated at the rate of 3 inches per hour, reports NBC News. Airports in New York were closed for the day and hundreds of flights were canceled in Boston.

The snow and wind also brought flooding, car accidents and power outages.
