Rain Totals Released From Bay Area Storm As Region Braces For More Rain, Wind

SAN FRANCISCO — A powerful cold front is bringing heavy rain, gusty winds and even a slight chance of waterspouts to the Bay Area early this week, according to the National Weather Service.

Saturday marked the beginning of a series of storms expected to douse the Bay Area.

Scattered showers and the possibility of thunderstorms are expected through Monday. Forecasters said surface‑based instability could allow updrafts strong enough to produce brief bursts of rain at 0.25 to 0.50 inch per hour.

As the front moves in, meteorologists are watching systems move over coastal waters, which they say could raise the risk of waterspouts making landfall along portions of the San Mateo Peninsula and Monterey County.

"While narrow and fast-moving, the main band of rain has been intense, with a weather spotter in Marin reporting over six tenths of an inch in less than an hour," NWS forecasters in the Bay Area wrote Monday. " These high rain rates could cause some landslides, especially after the recent wet weather."

Isolated to scattered rain showers and a slight chance for thunderstorms will continue through Monday afternoon. Chances diminish as we head into tonight and more so Tuesday morning. Dry conditions return by late Tuesday morning. #CAwx #BayAreaWX pic.twitter.com/6n1bNYxoID

Forecasters said that the threat is highest over the Pickett Burn Scar in Napa County, where a flash flood warning was in effect Monday morning. Winds have also been gusting to "gale force" through the region, forecasters said.

The heaviest rainfall is expected to taper off later Monday night into Tuesday, making way for another system. That storm will likely bring “beneficial” rain by late Wednesday into Thursday, forecasters in the Bay Area said. While it’s not expected to be as strong, forecasters say the wet ground from days of rain will increase the risk of additional land or rockslides.

That said, here are the rainfall totals across the Bay Area over the last 24 hours:

• Dublin: 0.83 inches
• Livermore: 0.51 inches
• Fremont: 0.73 inches
• Milpitas: 0.59 inches
• Castro Valley: 0.92 inches
• Palo Alto: 0.59 inches
• San Francisco International Airport: 1.31 inches
• San Francisco: 0.84 inches
• Mill Valley: 0.95 inches
• Novato: 0.68 inches
• Petaluma: 0.71 inches

The NWS is also predicting very high surf for late Thursday into Friday, as a strong northwesterly swell develops. The warning comes just a father died trying to save his daughter over the weekend after she was swept into the ocean amid high surf.

A volunteer diver recovered the body of the girl around 1:20 p.m. Sunday, about a half-mile north of where she went missing at Garrapata State Park in Monterey County, according to California State Parks and the Monterey County Sheriff's Office.
