Did the storm blow off a roof of an apartment complex in South San Francisco? Kind of.

Around 2 a.m. Tuesday, winds kicked up in San Mateo County with reported wind gust of up to 70 mph at San Francisco International Airport. S

hortly after, 911 callers reported that roof damage at a four-unit complex on Susie Way in South San Francisco, said Matt Samson, the city’s deputy fire chief.

Upon arrival, crews discovered that wind removed the outer layer of the roof – which Samson referred to as the water-proofing membrane.

“It’s a flat roof,” Samson said. “Then on top of that is a water proofing membrane that keeps the rain out and that’s what was separated. Crews arrived and made sure all the residents were safe and were able to evacuate them out the building without any injury.”

The residents of the two units on the bottom floor were able to return to their units, but 10 residents of the two upper units were moved to a shelter due to water damage, Samson said.

Rescuers have ended the search for a 5-year-old boy who was swept away by floodwaters in central California Monday morning, the Associated Press reports. A roughly 7-hour search for the missing boy turned up only his shoe before officials called it off as water levels were too dangerous for divers, officials said. The boy has not been declared dead, said spokesperson Tony Cipolla of the San Luis Obispo County Sheriff’s Office. The boy’s mother was driving a truck when it became stranded in floodwaters just before 8 a.m. near Paso Robles, a small city inland from California’s central coast, according to Tom Swanson, assistant chief of the Cal Fire/San Luis Obispo County Fire Department. Bystanders were able to pull the mother out of the truck, but the boy was swept out of the vehicle and downstream, likely into a river, Swanson said. There was no evacuation order in the area at the time.

This map shows where hundreds of S.F. trees have fallen

A wave of recent storms brought heavy winds and rainfall to the Bay Area, causing flood damage and power outages. Data shows that San Franciscans are also dealing with a huge spike in fallen trees as a result of recent inclement weather.

Extreme winds from the atmospheric river storm last Wednesday downed numerous trees, disrupting traffic and disabling electrical lines.

Data from the city’s 311 database shows that the highest number of reports were made on Wednesday, Jan. 4, at 114. The following day, 78 reports about fallen trees were called in. Read more here about reported fallen trees in San Francisco.

Russian River avoids flood levels

A series of atmospheric rivers took more southerly routes than predicted, dumping far less rain on the North Bay region so far this week. Models show the Russian River crested about 5 a.m. today just below flood stage at 31.8 feet.

But with more rain in the forecast, people should remain alert, said National Weather Service meteorologist Cindy Palmer. Mudslides, falling trees and some flooding are still major risks given that the ground is is saturated and the creeks are overly full.

“We’re going to be monitoring the rivers streams and creeks closely,” Palmer said. “We are not out of the woods just yet.”

“It felt like our house was gonna blow away”

People in Northern California were woken up starting around 2 a.m. by intense rain and, in some cases, thunder.

From Oakland to the Tri-Valley to San Francisco, people on social media said the sounds and sights of the storm were like nothing they had seen before.

In the East Bay, one Reddit user wrote: “That might have been some of the hardest hitting rain I’ve ever heard.”Others also woken up by the storm concurred: “It had me looking out the window thinking ‘what would happen if that tree fell on the house?’ I’ve never heard wind like that before.” Another user wrote they “saw and heard one intense lightning/thunder and it felt like our house was gonna blow away.”

A Campbell resident said a redwood tree uprooted and fell into the corner of their building: “This is where our bedroom is, so we’ve moved to our spare. Not sure what the extent of the damage is, but it’s holding for now. I imagine that this will take days to have removed.”

Hail reported in San Francisco 

A storm system moving across the Bay Area early Tuesday morning brought hail to San Francisco, according to multiple reports.

PG&E outages: 189,000 customers without power 

About 189,000 Pacific Gas & Electric Co. customers were without power Tuesday morning after the latest round of winter storms pounded the Bay Area and the Central Coast, according to the utility company. 

“The storm activity included wind gusts exceeding 70 mph and more than 100 cloud to ground lightning strikes as of 5:30 a.m.” Tuesday, PG&E said in a morning update. 

Morning storms could bring hail to parts of Bay Area 

The next storm system set to rake across the Bay Area is expected to bring scattered thunderstorms Tuesday, along with gusty winds and even small hail, according to a forecast from the National Weather Service. 

The storms are likely to lose steam throughout the day and taper off Tuesday evening, NWS said. “Another round of rain and gusty winds appears on tap for Wednesday, then drier conditions as we head into the latter part of the week,” NWS meteorologists wrote.

How high will rainfall totals be in the Bay Area?

Rain totals will likely tally around 1 to 2 inches in most of the Bay Area, says Chronicle meteorologist Gerry Díaz says, while the mountains could see as much as 4 inches as thunderstorms rain themselves out between valleys. It goes without saying that the additional rain and the strong winds from all these thunderstorms will only add to the stress on soils that are filled to the brim with moisture, along with the risk for debris flows as oversaturated trees fall over. 

Tuesday’s weather forecast

Monday night’s thunderstorms will carry over into Tuesday morning, bringing rounds of heavy downpours, lightning and strong winds to the Bay Area and Santa Cruz Mountains. Unlike recent storms, Tuesday’s setup will host on and off rounds of heavy rainfall. This means that there will be places across the Bay Area where breaks in the rain might last anywhere from a couple minutes to a couple hours, depending on how many thunderstorm cells end up forming.

Dozens of Teslas and other high-end cars ruined by storm flooding at S.F. repair shop

More than a week after the epic New Year’s Eve storm sent waist-high waters coursing through Alioto’s Garage on Folsom Street in San Francisco, the garage is still cleaning up – but 40 Tesla, Porsche and other pricey cars that got flooded are a total loss. Garage co-owner Matt Alioto said the local storm drain backed up in the storm and turned his repair shop into a little lake so fast that he and his staff couldn’t move the automobiles out of harm’s way. “We’ll probably be cleaned up enough to start taking cars in by the end of this week, or next week, but the damage is in the hundreds of thousands of dollars,” Alioto told The Chronicle.

Sewage overflows into San Francisco Bay and city streets

Millions of gallons of storm water mixed with raw sewage made its way into creeks, the bay and city streets during recent heavy rainstorms that overwhelmed dozens of Bay Area sewers and some treatment plants.

Some raw sewage seeped out of manholes or backed up sewer drains, calling into question even the idea of kids splashing in their rainboots.

“Don’t jump in puddles. Especially in San Francisco — you want to be careful that there (could be) sewage in that,” said Eileen White, executive officer of the San Francisco Bay Regional Water Quality Control Board, referring to flooded areas when the city’s unique sanitary system that combines storm water and wastewater is backed up during heavy rain.
