Stormy winds and acres of snow are blanketing the eastern United States today (Dec. 23) within view of satellites.
Weather forecasters are trying to assist travelers and holiday-goers with staying safe amid the dangerous conditions using satellites gazing at the United States from the National Oceanic Atmospheric Administration (NOAA) and NASA.
High winds were visible in NOAA's Geostationary Operational Environmental Satellites (GOES)-East or GOES-16, a satellite in geosynchronous orbit. "Red is high-level, blue mid-level, and yellow is low-level wind," NOAA said in a tweet (opens in new tab).
Roughly 60 percent of the United States population, or 200 million people, have winter weather warnings or advisories, the National Weather Service (NWS) said in a tweet (opens in new tab). The scale of the storm produced "one of the greatest extents" of warnings or advisories in the history of the service, NWS added (opens in new tab) on their website.

The weather service says a "powerful Arctic front" is behind the storm's power, bringing heavy snows to the Great Lakes and winter weather hazards even in the Gulf Coast and the central Florida peninsula.
Bitterly cold wind chills are going into zones like the Carolinas, where the population may not have the infrastructure to deal with it, while regions like Buffalo are being walloped with snow.
The winter storm has already knocked out power to at least a million customers across the country, the New York Times said (opens in new tab), and parts of Canada are also dealing with unusual winds and snow that are bringing travel disruptions, even in regions that are equipped for severe winter weather.
Airports across the U.S. and Canada have canceled or delayed flights on what is usually one of the busiest days of the year, and disruptions are expected to persist through the weekend at the least.
