The system, which brought tremendous amounts of snow and rain to California, is expected to dump feet of snow in the central U.S. Forecasters expect the storm to hit the Northeastern U.S. by Monday.
The Northeast dealt with canceled flights and power outages Thursday after heavy snowfall. Rain fell hard in Southern California and residents remained alert to the risk of mud and debris flow.
It's a rough start to spring for residents on both sides of the country. Southern Californians braced for rain and potential mudslides while residents of the Northeast dealt with heavy snow Wednesday.
While the storm had moved offshore Saturday, flood threats remained, especially along coastal Massachusetts, where crews have rescued scores of people. The governor has declared a state of emergency.
A nor'easter pounded the East Coast Friday. In California, a storm likely will drop feet of snow in the mountains, but a threat of major mudslides seems to have passed.
The "bomb cyclone" is expected to move up the coast from Florida to Maine, but its impact on the East Coast depends on how far west it tracks and how wide of a swath it cuts.
The storm swept through the Mid-Atlantic and Northeast on Tuesday, leaving more than 200,000 utility customers without power and some 6,000 canceled flights in its wake.
The potentially historic nor'easter could bring more than 2 feet of snow to the region today and Tuesday. Travel is expected to be affected, with thousands of flights already canceled.
