‘Outrageous’ rainfall possible in Big Sur
Reeve Mendocino “can’t catch a break.”
Residents of rural Mendocino County have been under siege by the weather for weeks, stuck in snow and feeling the latest storm piles misery upon misery.
The Healthy Start Community and Family Resource Center in Laytonville was busy Thursday with volunteers loading boxes of food, batteries and other supplies into trucks for emergency crews to deliver to people trapped in the nearby hills.
“We are preparing from having feet of snow to feet of water,” said center director Jayma Shields. “We can’t catch a break. People have been stuck in the hills for at least 10 days, out of propane, food and pet food.
Some residents at elevations of 3,000 feet were drenched in 7 feet of snow, she said, and now there’s a fear that heavy rains could cause flooding as the snow melts.
The storm fluctuated as it approached the Bay Area this morning, with some early rain bands starting to fall about an hour later than yesterday’s forecast for the timing of the initial rain bands. But the abundance of these protocells off the coast is also an indicator of a healthy storm. This means the Bay Area will begin to see more widespread rain and wind as severe weather conditions increase over the next 60 to 90 minutes.

Pineapple expresses severe weather in the coming week
The Pineapple Express-fueled storm will bring a series of severe weather impacts to the Bay Area, including rounds of heavy rain, strong winds, thunderstorms and flooding. These effects will reach their peak during the night hours of Thursday and Friday. Conditions will begin to improve by Friday morning as the storm subsides, leaving light rain across the region through the weekend.
But another storm system will approach Northern California starting Sunday night. This system will tap into the Pineapple Express and spark another round of severe weather across the Bay Area on Monday and Tuesday. Weather models will begin to reveal details surrounding next week’s storm with high-resolution simulations, including thunderstorm intensity, winds and precipitation.
For now, it looks like next week’s storm will bring similar impacts to the Bay Area, including the risk of more river flooding in the North Bay and Santa Cruz Mountains.
The storm expected to hit the Bay Area on Thursday prompted San Mateo County officials to close several parks that were hit hard by storms in January. Officials said. The closure begins on Thursday and continues until Sunday.

The Upper Knoll and Eucalyptus Conservation Areas at Coyote Point Recreation Area in San Mateo are closed, but the park, beach and Magic Mountain will remain open. These parks have a “significant number” of downed trees, trail damage, mud and road slides, officials said, from storms in January.

Some Bay Area residents woke up to light rain Thursday morning and expect heavy rain late in the morning to early afternoon, the National Weather Service said.
“That’s when we start to have some concerns about street and creek flooding, and then the flood concerns will continue into next week with another round of rain early next week,” said Sean Miller, a meteorologist with the National Weather Service.
Weather models indicate an early start to Thursday’s winds, with winds expected to reach 35 to 45 mph along the coast right around sunrise. These winds will blow from the southwest, bringing rain from the Pineapple Express storm. Rain will begin after 7 a.m. on the beaches of Sonoma, Marin and San Mateo counties while winds blow stronger throughout the morning.
Winds will continue to pick up along the coast after 10 a.m., gusting to 50 mph on the west side of San Francisco and on beaches from Sonoma County to Santa Cruz County. Winds across the broader Bay Area will also begin to gust between 35 and 45 mph, as rain showers begin to spread across Northern California.
SF Chronicle meteorologist Jerry Diaz provided a comprehensive report A timeline of what to expect across areas of the Bay Area in today’s forecast. Here’s the TLDR version:
The North Bay Highlands and Santa Cruz Mountains will see a slight uptick in precipitation after 10 a.m., then heavy rain is likely throughout the rest of the day.
Heavy rain will also spread to San Francisco, Oakland, and the inland valleys of the North Bay and East Bay.
Urban flooding will be possible along highway ramps and low lying highways, along with ponding.
The heavy rain will be accompanied by a chance of thunderstorms capable of producing damaging winds and hail this afternoon.
Rush hour commuting can be difficult, as the strongest rain and wind bands affect cities along the San Francisco Bay.
In most of the Bay Area, the rain and wind won’t let up tonight, so plan for a windy Thursday night if you have to get out.
