This Geocolor image from the National Oceanic and Atmospheric Administration (NOAA) GOES-16 satellite captures the deepening storm off the East coast of the United States on Jan. 4, 2018, at 16:22 UTC. The powerful nor’easter is battering coastal areas with heavy snow and strong winds, from Florida to Maine. Notice the long line of clouds stretching over a thousand miles south of the storm, which is drawing moisture all the way from deep in the Caribbean.
