Satellites Track Huge Snow Storm’s Approach to US East Coast

As a winter storm prepares to wallop the East Coast tonight and tomorrow (March 13 and 14), NASA and the National Oceanic and Atmospheric Administration (NOAA) are keeping a close eye on the region with multiple satellites.

The latest predictions from the National Weather Service say a low-pressure system crossing the Midwest states and the Ohio Valley will merge with another low-pressure system off the southeast coast of the U.S. You can see a video of the storm as seen by the GOES-16 satellite here.

“This will allow for a strong nor’easter to develop near the coast and cause a late-season snowstorm from the central Appalachians to New England, including many of the big cities in the Northeast U.S.,” according to forecasters from the National Weather Service Weather Prediction Center (WPC) quoted in a statement from NASA.

“The heaviest snowfall is expected to occur from the northern Middle Atlantic to southern New England, where 12 to 18 inches [30 to45 centimeters] can be expected with localized amounts up to two feet [0.6 meters],” according to the WPC. “Strong winds could down trees and cause power outages.”

From southern New Jersey to the Carolinas, residents can expect more than an inch of rain, according to the statement.

NASA’s Aqua Satellite has already gathered infrared data — or heat data — on the storm, showing cloud top and ground temperatures. As cloud tops get higher, they also get colder and can strengthen a storm, the NASA statement said.
