Another bout of rain and mountain snow will cause travel disruptions across the western United States into Friday.
Moisture from the Pacific Ocean will continue to stream inland to end the week.
Soaking rain will fall along the Interstate-5 corridor from Seattle to Sacramento, California, into Thursday night.
The rain will pivot southward into central California on Thursday night, eventually reaching Southern California later Friday. Some rain will expand inland into Nevada and Utah.
Localized flash flooding, mudslides and rock slides will be possible across Northern California, where the heaviest rain will take aim.
“Combined with soggy ground, strong winds could topple trees and cause sporadic power outages from northern California to western Washington,” AccuWeather Meteorologist Faith Eherts said.
Winds could whip past 50 mph along the the coast and over the mountainous terrain.
The winds will push a large amount of water toward the coast, leading to dangerous surf, beach erosion and possible coastal flooding.
Over the higher terrain, cold air will rush in and cause a quick changeover from rain to snow across the Cascades and Sierra Nevada.
“Rain is in store for Donner Pass in California until the tail end of the storm on Friday,” Eherts said.
Motorists should be prepared for wet portions of interstates 80 and 90 that could quickly freeze and become snow-covered on Thursday night.
East of the Cascades, freezing rain can fall for a time over central Washington before a change to all rain occurs later Thursday.
The stormy weather to end the week will cap off an unsettled start to February across the West Coast.
Rain has fallen every day through the first eight days of the month in San Francisco, Redding and Eureka, California, and Medford, Oregon.
The West Coast will finally begin to dry out over the weekend and into early next week as unsettled weather sinks southward across the Southwest.
