Forecasters in the US warned that another round of winter weather could complicate travel ahead of Thanksgiving, as the states of California and Washington continue to recover from storm damage and power outages.

In California, where a person was found dead in a submerged vehicle on Saturday, authorities braced for more precipitation as they dealt with flooding and small landslides from an earlier storm.

The National Weather Service in Sacramento, California, has issued a winter storm warning for the state’s Sierra Nevada from Saturday through Tuesday, with heavy snow expected at higher elevations and wind gusts possibly reaching 55 miles per hour. Total snowfall of around 1.2 meters was forecast, with the heaviest accumulations expected on Monday and Tuesday.

The Midwest and Great Lakes regions will see rain and snow on Monday, and the East Coast will be hardest hit on Thanksgiving and Black Friday, forecasters said.

A low-pressure system is expected to bring rain to the southeast early Thursday before moving northeast. Areas from Boston to New York could experience rain and windy conditions, with snowfall possible in parts of northern New Hampshire, northern Maine and the Adirondacks. If the system moves further inland, less snow and more rain could fall in the mountains, forecasters said.

“The system doesn’t look like a powerhouse right now,” Hayden Frank, a meteorologist with the National Weather Service in Massachusetts, said Sunday. “In principle, this will bring rain to the I-95 corridor, so travelers should prepare for wet weather. Unless the system gets much colder, it will look like rain.”

Frank said he doesn’t see any major storm systems arriving anywhere in the country this weekend, so travelers heading home on Sunday can expect good driving conditions. However, temperatures will get colder in the east, while warming in the west.

About 36,000 people in the Seattle area were still without electricity after the season’s strongest atmospheric river, a long plume of moisture that forms over an ocean and flows over land.

Another storm brought rain to New York and New Jersey, where rare wildfires have raged in recent weeks, and heavy snow to northeastern Pennsylvania. The precipitation was expected to help alleviate the drought after an exceptionally dry autumn.

“It won’t be drought relief, but it will certainly help if this all melts,” said Bryan Greenblatt, a National Weather Service meteorologist in Binghamton, New York.

Heavy snow fell across northeastern Pennsylvania, including the Pocono Mountains. Higher heights reported up to 17 inches, with smaller accumulations in valley cities including Scranton and Wilkes-Barre. About 35,000 customers in ten provinces are still without power, compared to 80,000 a day ago.

In the Catskills region of New York, nearly 10,000 people were without power Sunday morning, two days after a storm dumped heavy snow on parts of the region.

Rainfall in West Virginia put a dent in the state’s worst drought in at least two decades and boosted ski areas preparing to open their slopes in the coming weeks.
