Winter Storm Gorgon, which has already brought snow to the Northwest and Northern Rockies, has traveled across the country bringing snow to the Mid-Atlantic coast.

This fast-moving system has already prompted winter storm watches, warnings, and advisories for parts of 22 states from Washington all the way to New Jersey, as well as the District of Columbia.

Gorgon lost some of its punch as it moved into the Northeast, but light snow interrupted the morning commute in Philadelphia, Baltimore, Washington, D.C. and New York City.

Gorgon's first target was the state of Washington, where 11.2 inches of snow fell at Chief Joseph Dam in central Washington. The system also brought to parts of western Washington, causing mudslides that have left people stranded and roads closed. Heavy rain caused a string of mudslides in western Washington on Monday, including one that forced emergency crews to rescue an elderly woman and her dog by cutting a hole in her roof.
