SAN FRANCISCO (KRON) – An Atmospheric River continues to soak the Bay Area Monday morning, with multiple weather alerts including Wind Advisories in effect across the region.


Wind Advisories are currently in effect for the San Francisco Peninsula, Santa Cruz County, and the South and East Bay, according to the National Weather Service Bay Area.

A Wind Advisory for parts of the Bay Area has been extended through Monday afternoon. It was previously set to expire Monday morning.

A High Surf Advisory is also in effect until Wednesday morning.

A Flash Flood Warning was issued for portions of San Mateo and Santa Cruz Counties but has since expired.

The heaviest rainfall is expected this morning through 9 a.m., KRON4 meteorologist John Shrable said.

Rain will hit the Bay Area in waves, he added, with the first wave happening Monday morning and the second wave expected early afternoon as pockets of moisture push through.

Tuesday morning, pockets of heavy rain but will be isolated and scattered. Things dry out Tuesday afternoon, before another chance of a few showers on Wednesday.

Caltrans closed Highway 1 on the Big Sur Coast, between Ragged Point in San Luis Obispo County and Deetjen’s Big Sur Inn in Monterey County, at 8 p.m. Sunday. The closure is expected to remain in effect until Tuesday, when the transit agency will assess the conditions.

Officials issued evacuation warnings around the Dolan Fire burn scar Sunday night, as mudslides and downed trees and power lines are possible. Caltrans said it’s working with local agencies to minimize travel into Big Sur to allow residents and businesses to evacuate in the safest conditions possible. The closure of Highway 1 comes at the request of the California Highway Patrol.

Monterey County issued an evacuation warning around 5 p.m. Sunday for the Dolan burn scar area and areas in and around River Road in Salinas until Tuesday morning, as Sunday’s atmospheric river storm system dumps heavy rain in the county.

Forecasters say rainfall will likely meet thresholds for increased risk of debris flow activity, especially in areas near the fires of Aug. 2020. Properties and people located below or downstream of the burn areas are at an increased risk.

Areas affected by the warning include Pine Canyon Road, Trimble Hill, Mesa Road, Manzanita Way, Wildwood Way, Redding Drive., Belmont Circle, the southwest end of Berry Drive, Limekiln Road and the 800 Block of River Road. For large animal evacuation resources and information contact the SPCA for Monterey County at (831) 646-5534.

The National Weather Service reported heavy snow across the western slopes and passes of the Sierra Nevada night, with chain controls in effect for the higher elevations of I-80, Hwy 50, and Hwy 88.

A winter storm warning is in effect until 10 p.m. Tuesday in the Greater Lake Tahoe area as Sunday marks the start of a five-day storm series in the Sierra Nevada, according to the National Weather Service.

An avalanche watch was also issued, with periods of high avalanche danger from Sunday evening through Wednesday morning between Yuba Pass (Highway 49) and Ebbetts Pass (Highway 4.) These conditions are the result of heavy snow loading on an already weak snowpack.

Monday snowfall is predicted to be heavy continuing into Tuesday. Yuba Pass to Donner Summit could see 60 to 72 inches of snowfall by Tuesday night, with Tahoe receiving up to 96 inches at higher elevations.

Wednesday may bring a brief break in the weather with a quick-moving system moving into the area on Thursday.

The precipitation will bring at least temporary relief to the broader region that’s been gripped by drought caused by climate change. The latest U.S. drought monitor shows parts of Montana, Oregon, California, Nevada and Utah in exceptional drought, which is the worst category.

Most reservoirs that deliver water to states, cities, tribes, farmers and utilities rely on melted snow in the springtime.
