A new NASA video of NOAA's GOES satellite imagery shows three days of
movement of the massive winter storm that stretches from the southern
U.S. to the northeast.
Visible and infrared imagery from NOAA's GOES-East or GOES-13
satellite from Feb. 10 at 1815 UTC/1:15 p.m. EST to Feb. 12 to 1845
UTC/1:45 p.m. EST were compiled into a video made by NASA/NOAA's GOES
Project at NASA's Goddard Space Flight Center in Greenbelt, Md.
In the video, viewers can see the development and movement of the
clouds associated with the progression of the frontal system and related
low pressure areas that make up the massive storm. The video also shows
the snow covered ground over the Great Lakes region and Ohio Valley
that stretches to northern New England. The clouds and fallen snow data
from NOAA's GOES-East satellite were overlaid 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.
On February 12 at 10 a.m. EST, NOAA's National Weather Service or NWS
continued to issue watches and warnings from Texas to New England.
Specifically, NWS cited Winter Storm Warnings and Winter Weather
Advisories were in effect from eastern Texas eastward across the
interior section of southeastern U.S. states and across much of the
eastern seaboard including the Appalachians. Winter storm watches are in
effect for portions of northern New England as well as along the
western slopes of northern and central Appalachians. For updates on
local forecasts, watches and warnings, visit NOAA's www.weather.gov webpage.
NOAA's Weather Prediction Center or WPC noted the storm is expected to
bring "freezing rain spreading into the Carolinas, significant snow
accumulations are expected in the interior Mid-Atlantic states tonight
into Thursday and ice storm warnings and freezing rain advisories are in
effect across much of central Georgia.
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.
