National Weather Service forecasters have been tracking a low pressure area that moved from the Midwest into the Atlantic Ocean today, and is expected to become a strong nor’easter that will bring blizzard conditions to the northeastern U.S.
The path of the system was captured in a NASA movie of NOAA’s GOES-East satellite imagery.
On Monday, January 26, 2015, the National Weather Service noted: A storm system off the East Coast will continue to strengthen as it develops into a major nor’easter on Monday. As the storm moves up the coast, it is expected to bring snowfall of 1-3 feet or more to many parts of the Northeast through Tuesday evening, including New York City and Boston. Strong, gusty winds will combine with the snow to create blizzard conditions along and near the coast.
Winter storm warnings are in effect for the panhandles of West Virginia and Maryland, much of interior New England down to the northern Mid-Atlantic as well as for Nantucket Island, Massachusetts. Winter weather advisories are in effect for portions of the Ohio Valley, Mid-Atlantic and the southern Appalachians as well as a narrow area across interior New England.
To create the video and imagery, NASA/NOAA’s GOES Project located at NASA’s Goddard Space Flight Center in Greenbelt, Maryland overlays the cloud data from NOAA’s GOES-East satellite on a true-color image of land and ocean created by data from the Moderate Resolution Imaging Spectroradiometer, or MODIS, instrument that flies aboard NASA’s Aqua and Terra satellites. Together, these data create the entire animation of the storm and show its movement.
GOES satellites provide the kind of continuous monitoring necessary for intensive data analysis. Geostationary describes an orbit in which a satellite is always in the same position with respect to the rotating Earth. This allows GOES to hover continuously over one position on Earth’s surface, appearing stationary. As a result, GOES provide a constant vigil for the atmospheric “triggers” for severe weather conditions such as tornadoes, flash floods, hail storms and hurricanes.
