California and other parts of the West faced heavy snow and rain Friday from the latest winter storm to pound the U.S., while thousands of people in Michigan shivered through extended power outages wrought by one of the worst ice storms in decades.
The National Weather Service warned of a “cold and dangerous winter storm” that would last through Saturday in California.
The most powerful storm in more than a decade will hit San Diego County late Friday and early Saturday with snow that could cause whiteout conditions in the mountains and shut down Interstate 8, rain that could cause widespread flooding and mudslides, and winds that could make kindling out of trees, the National Weather Service said.
A powerful storm is expected to sweep across California this week, bringing cold temperatures, cutting winds and snowfall at remarkably low elevations nearly statewide.
“This is shaping up to be a very unusual event,” UCLA climate scientist Daniel Swain said in a virtual briefing Tuesday morning. “We are going to see low [elevation] snow all the way from the Oregon border to the Mexican border — it’s just a question of how low.”
If you thought San Diego County was off to a particularly wet start to the new year, you’re absolutely right. The National Weather Service said with January, the region experienced its wettest month since February 2005.
Winter storms brought measurable rain to the county last month, bringing a rain total of 5.14 inches, according to the agency. The average January rainfall in San Diego is 1.98 inches, to give you a better idea of how wet conditions have been.
Rainfall was starting to roll into the San Diego area Tuesday morning as part of a new wave of storms expected throughout the week, according to the National Weather Service. Clouds were thickening with partly and mostly cloudy skies expected to blanket Southern California on Tuesday, growing denser as the frontal system over the eastern Pacific approaches the area.
As the United States begins to recover from a week of severe weather that left dozens dead, more storms are already in the forecast. An atmospheric river began moving through California on Tuesday, with another atmospheric river predicted for later in the week.
The first of two Pacific storms will push into San Diego County on Tuesday night and likely drop a half-inch or more of rain at and near the coast and slightly more in the foothills and mountains by early Wednesday, says the National Weather Service. The rain represents the tail of a much larger system that is soaking the Bay Area and is expected to bring heavy snow to the Sierra Nevada, benefiting many of the state’s reservoirs.
Utah saw a snowy start to December, which is an encouraging sign for a state experiencing ongoing drought. But experts say it’s still early, and even if Utah has an above-average winter, it’ll take several strong years to make up for a multi-year water deficit.
A storm blanketed the Sierra Nevada in heavy snow and soaked much of California with rain, bringing a wet start of winter weather after three years of record drought. The storm brought 3 to 4 feet of fresh snow in parts of the Sierra Nevada over the weekend. From the San Francisco Bay Area to Southern California, between 1 inch and 4 inches of rain fell in many areas.
Boosting what has been a mediocre start so far to the winter season, a storm from the Pacific Northwest is expected to bring widespread rain to the Bay Area early Thursday and blanket the Sierra Nevada with up to 3 feet of new snow. “This is a pretty good event. It’s going to be beneficial across the board,” said Brayden Murdock, a meteorologist with the National Weather Service in Monterey. “We are excited for this one.”
