It's a #snowday in the nation's capital captured here by #GOESEast. @NWS_BaltWash reporting conditions will rapidly deteriorate this morning, with snowfall rates up to 2" per hour over the next few hours in some areas, for our first full day of #Spring! pic.twitter.com/geBgnyulnV— NOAA Satellites (@NOAASatellites) March 21, 2018
A massive storm is expected to dump more than a foot of snow in some states along the northeastern U.S. coast, and satellites are tracking the snowfall from space.

"It's a #snowday in the nation's capital captured here by #GOESEast," NOAA officials wrote on Twitter in a post that included a video of the storm system in action. Conditions in the Baltimore area were expected to deteriorate rapidly over the morning, with some regions receiving 2 inches (5 centimeters) of snow per hour, NOAA officials added.
Another short animation from GOES-East showed the storm engulfing states from North Carolina up to Massachusetts.
"#GOESEast captures the start of the storms affecting parts of the East Coast and expected to bring heavy snow to the start of Spring," NOAA officials wrote.

The National Weather Service has issued a winter storm warning through Thursday morning (March 22) due to today's snowstorm, which is the fourth nor'easter to hit the U.S. East Coast in March. Some regions could see between 12 and 18 inches (30 to 46 cm) of snow, according to the National Weather Service.
The GOES-East satellite, also called GOES-16, launched in 2016 and is the first of two advanced Earth-observation satellites to improve weather forecasts. Its partner, the GOES-S satellite, launched into orbit on March 1 and will be known as GOES-West and GOES-17 when it begins operation. GOES is short for "Geostationary Operational Environmental Satellite."
