Many Californians will wake up this morning to a relatively rare phenomenon: Rain. Today, the freezing-cold temperatures and high-powered winds that have gripped much of the state this week are set to give way to a good old-fashioned winter storm: Both Northern and Southern California are expecting rain, strong winds and heavy mountain snow, with an avalanche warning in effect through Friday for backcountry areas in the Sierra Nevada.
A Pacific storm that was expected to drop about 1.5 inches of rain along the San Diego County coastline has produced more than twice that much and will continue to wash across the region until Friday night, according to the National Weather Service.
The system arrived in force on Sunday and was supposed to be gone by Wednesday night or Thursday at the latest.
“But it’s been sitting and spitting over us all week”, said Miguel Miller, a weather service forecaster “The models have it moving out pretty quickly on Friday night.”
San Diego International Airport unexpectedly received about 1.50 inches of rain overnight. By 6 a.m. Friday, the airport’s seasonal rainfall total had hit 12.54 inches, more than three inches above average.
Through the past week, much of Southern California has experienced an offshore breeze, promoting above-average temperatures. Heading into the first full week of February, that will change as this storm system tracks through. A major storm system that is expected to bring feet of snow to the Intermountain West will usher in potentially damaging wind gusts to Southern California. Powerful north-to-northwest wind gusts will pick up in earnest late Sunday across Southern California and Nevada, leading to localized power outages and travel issues.
A storm system from the Gulf of Alaska is poised to make Wednesday night in the Bay Area wet and windy.
The system is expected to deliver winds with gusts of up to 40 miles per hour and rain across the region, starting in the North Bay around sunset before moving south. Up to 2 feet of snow could fall in parts of Northern California and the Sierra, according to the National Weather Service, while local precipitation is expected to continue through Thursday, when showers give way to a cloudy Friday.
Normally sunny San Diego got more rain than Seattle last month, a reverse of what residents of both West Coast cities have to come to expect.
The National Weather Service recorded just under 3 inches of rain with their monitoring station at Lindbergh Field this November, making it the wettest November on record for San Diego.
San Diego County will experience a second day of heavy rain Wednesday from a cold storm out of the north that tapped into tropical moisture from the south as it surged into Southern California, according to the National Weather Service.
The entire region will get soaked, and all areas are under a flash flood watch. But the rain will be heaviest in northern and central San Diego County, especially along Interstate 15, from roughly Escondido north to the county line, forecasters say.
