Precipitation began Sunday in the form of a wintry mix in New York City before changing to rain, but more ice and snow north and west led to slick roads in many areas.
The powerful storm made its way east from California and is causing major disruptions around the country as people headed home after Thanksgiving.

The storm that hit much of the central U.S. with blizzard conditions Saturday is bringing snow, ice and the potential for flash flooding in a large portion of the Northeast.
The National Weather Service said travel could become impossible in some places.
The weather was particularly disruptive on Sunday as millions of holiday travelers headed home. Airlines for America, the airline industry's trade group, expected 3.1 million passengers during what could be the busiest day ever recorded for American air travel.
By Sunday afternoon there were over 500 canceled flights in the US, and the FAA said some flights heading to Newark were being delayed by an average of more than 2 1/2 hours.
New York Governor Andrew Cuomo placed National Guard personnel on standby and activated the state's Emergency Operations Center to enhanced monitoring mode as the storm arrived in the state.
Bus service was cancelled out of Port Authority in New York City to Binghamton, Rochester, Buffalo, Ithaca and Syracuse.
Winter Storm Warnings are in place across the tri-state area through Tuesday.
