The bomb cyclone that hit the Bay Area on Wednesday drenched Palo Alto and East Palo Alto with heavy rain and winds. The weather event led to downed trees and arcing power lines that closed roads and knocked out power to thousands of residents.

Wednesday’s major storm came roaring in late in the afternoon and early evening, with wind-driven rain pelting the Bay Area. A high-wind warning is in effect, with wind speeds of 20 to 30 mph and gusts of 40 to 50 mph expected in the valley areas; wind speeds for the mountains were forecasted at 30-40 mph with 60-70 mph gusts through 10 a.m. Thursday, according to the National Weather Service.

The storm, which meteorologists predict will last through late Thursday afternoon, dumped 1.1 inches of rain in Palo Alto between Wednesday and Thursday mornings and more than 2 inches in the Santa Cruz Mountains, according to the National Oceanic and Atmospheric Administration. But rain that was predicted to exceed the Dec. 31 storm and potentially cause San Francisquito Creek to overtop again on Wednesday night didn’t materialize. The water levels were at about 50% of capacity for San Francisquito, Matadero and Adobe creeks during the peak of the storm.

The atmospheric river still created outages, downed trees and roadway flooding, which caused some street closures. Wind was the largest factor, causing trees to fall and branches to snap, some onto power lines.

The evening started with periods of heavy rain that caused some street flooding. Police closed northbound El Camino Real at the University Avenue underpass due to water at around 5:50 p.m. and remained blocked as of late Thursday morning. Earlier on Wednesday, the underpass had been open except for one lane in each direction.

Four inches of water were reported at about 6:30 p.m. at the intersection of Illinois Street and Purdue Avenue in East Palo Alto and flooding also occurred at Elwell Court and East Bayshore Road, according to police dispatchers.

An 80-foot-tall tree that was 20 inches in diameter blocked Page Mill Road between Hanover Street and Peter Coutts Road at 5:55 p.m. All lanes were closed in both directions due to the tree and a disabled vehicle.

Starting at 6:20 p.m., a series of power outages grew from 70 customers to more than 3,000 in Palo Alto after high winds toppled trees, downed power lines and caused branches to land on lines, causing electrical arcing. In East Palo Alto, more than 2,000 customers were without power. Multiple houses on Louis Road, Aspen Court and Evergreen Road were evacuated due to a live power line that started a fire.

By 9 a.m. Thursday, about 160 Palo Alto and two East Palo Alto customers were still without power, according to Palo Alto Utilities and PG&E outage maps.

City crews from multiple departments worked throughout the night. Public Works employees responded to 33 calls concerning downed trees and 22 regarding flooding and storm drains. Utilities workers responded to 10 reported outages, which were all due to downed trees or branches, the city said in a Thursday morning update.

Palo Alto police and fire personnel responded to dozens of calls about storm-related vehicle collisions, alarms, road closures and other unsafe conditions. The city’s emergency dispatch center answered more than 300 total calls overnight. Fifteen people utilized the city’s Community Resource Center on Wednesday and overnight into Thursday morning.

After a night of high winds and toppling trees in Palo Alto, Tomm Marshall and Jorge Silva were out on Thursday morning surveying the damage and checking in on repairs to electrical lines.

Marshall, the city of Palo Alto Utilities’ assistant director of utilities, and Silva, the city’s electric operations manager, had been up all night working to restore power across the city.

In south Palo Alto, eucalyptus limbs in a backyard on Evergreen Drive had fallen at 10:15 p.m. on the electrical pole and wires, crashing into the secondary power lines and coming to rest there, Marshall said.

Given the hazard, the city turned off power to the block, and residents were evacuated for their safety.

On Thursday morning, the sounds of a chainsaw filled the air as a crew that included the Davey Tree company was busy figuring out how to remove the limbs without imperiling the electrical lines.

“It’s been fun,” joked Silva, standing on the sidewalk after a long night of work.

Until the tree is removed from the lines, the utilities crews can’t repair the damage and restore power.

The Evergreen scene was one of a handful that the city staff were working to address Thursday morning. Not far away, in the 3300 block of Middlefield Road, a large tree branch in another backyard tree had broken off after midnight and severed the electrical lines.

Though the storm’s rains were not as torrential as had been predicted by meteorologists, the wind caused all kinds of havoc.

“Wind is our enemy,” said Silva, noting that wind speeds peaked around 11 p.m. Wednesday, knocking out power in several areas.

The heavy rains for the past week have saturated the ground, Marshall added, and when that happens, trees are more easily toppling over in gusty winds.

More rain is expected through 3 p.m. on Thursday, with isolated showers and thunderstorms. A flood watch for Santa Clara and San Mateo counties is in effect until 4 p.m. on Thursday, according to the National Weather Service.

Here’s a breakdown of Wednesday’s and Thursday’s events, in reverse chronological order:

Thursday, Jan. 5

El Camino Real partially reopens — 4 p.m.: Two lanes, one in each direction, of El Camino Real at the University Avenue underpass have reopened. On Wednesday night, the northbound section had been closed due to flooding while the southbound section remained accessible. The city advised the public to be cautious when driving through the area.

Updates as of 11:30 a.m.:

Street closures: Northbound El Camino Real is closed at the University Avenue underpass for flooding. Southbound El Camino Real at that location remains open. Street signals might be out at other locations due to power outages. Motorists should treat dark, signalized intersections as four-way stops. All other road closures from the night before have since been cleared.

Overnight water flow in all creeks far below flood-warning levels: The flood risk remains low at this time, though rain and wind are expected to continue into the afternoon, the city of Palo Alto said in an online update. The city is monitoring the next storm, with more rain forecasted for Saturday and continuing intermittently through next week. Crews are working to address five remaining power outages, with restoration expected by this afternoon for most customers.

Community Resource Center remains open: Palo Alto’s Community Resource Center at Rinconada Library will remain open until at least 8 p.m. Thursday night to provide residents in need with a warm and dry location away from their home to relocate and gather. Visitors can also charge devices, use a laptop, find a hotel and determine next steps.

Prepare for additional power outages and stay safe on the roadways: The city of Palo Alto is asking residents to remain patient through Thursday’s storm and future forecasted storms. Residents can prepare for power outages by creating an emergency supply kit, filling their vehicle’s gas tank, and consulting their medical provider concerning any special medical considerations that may arise during an outage. A complete list of tips and resources related to outages is available at cityofpaloalto.org. Roadways might still contain standing water or fallen debris, and it’s important not to touch downed wires or move fallen branches, which may be entangled with live wires.

Wednesday Jan. 4

Flood warning expires — 11:45 p.m.: The National Weather Service announced that its flood warning has expired for Santa Clara County and other areas in central and northern California. “The heavy rain has ended. Flooding is no longer expected to pose a threat. However, additional rain showers are anticipated through early Thursday morning and water continues to recede from previous rainfall,” the National Weather Service said in a statement. “Please continue to heed remaining road closures.”

Fewer customers without power — 11:37 p.m.: The Palo Alto Utilities outage map now shows about 200 customers have lost service.

Wires down on Forest Avenue — 11:20 p.m.: Palo Alto firefighters responded to a report of wires down on Forest Avenue at Hale Street, where a tree was leaning on a power pole and wires were sparking, according to an emergency dispatch report. The tree was reportedly on fire, which was put out after power was shut off a short time later.

Palo Alto Utilities alert urges residents not to move tree branches — 11:19 p.m.: The Palo Alto Utilities Department sent out an alert urging residents to avoid moving any branches or trees due to live power lines that could be entangled. For any power-related emergencies, residents should call 650-496-6914.

Flood risk is low — 11:10 p.m.: While strong winds sparked power outages, the good news is that so far at least, the risk of flooding is low, with the city’s creek monitor showing water level well below capacity at some of the city’s most flood-prone areas. At the Pope-Chaucer Bridge, which has a capacity of 24 feet and which was pushed to the brink during last Saturday’s storm, the San Francisquito Creek stood at about 7.7 feet as of 11 p.m. And in the upstream area at Stanford University, which usually serves as a harbinger for future flooding in the more urbanized downstream areas, the water level was gauged at just over 4 feet, according to the U.S. Geological Survey. By comparison, the creek height at that location was measured at well over 12 feet on the morning of Dec. 31. “While rain will continue overnight, the flood risk is low,” the city announced in a 10:35 p.m. update. “Staff will continue to monitor creek levels overnight as a precaution.”

  1. Went out last night to take my empty sandbags to the Newell Street sandbox. It was wind-whipped already. It reminded me of Texas during a not-quite tornado. Enough wind to beat up the trees, but not enough to lift a house and carry it to Oz. So on my way back I did a little sight seeing. Which was idiotic. Road debris everywhere, branches chunking at my windshield. I do know better than this but it is pretty rare here. I would have taken some pics but heard a THUNK noise coming from the left rear end. I was sure whatever it was, was impaled because it scraaaaaaaaped all the way to the nearest parking lot, and i was going about 5 MPH.

    Luckily I did find my plastic pants and had them on, but was still grateful to have dry surface and lit surroundings to assess the damage. Apparently I grew a new kickstand, and it was permanently down. A tree branch had wedged itself between the coils on the strut and the pavement. Because I am so smart (not), I left all my go bag stuff at home, not anticipating needing any tools like a saw. I think I will write a short story about this. “A Storm, A Tree, and a Swiss Army Knife.” I guess this is why they said don’t go out unless necessary.

    It’s nice to have all of the storm related relief and information on one page like this article. Though none of them fit my particular calamity, I’m sure it worked for many. Staying home is the best plan.

  2. Thank you so much for the above information on flooding, wires down, road closures, power outages, etc.

    Another idea would be, a few days before an emergency, or even one day before, tell people to get gas, extra food and batteries in case we are stuck in our houses for a few days. Thank you.

  3. Kudos to the Weekly for all the useful pointers. I noticed that The Dirpy Post didn’t have nearly as much actionable information.

    If Palo Alto is going to mandate electricity only in new construction, are they also going to subsidize the purchase of backup generators for homeowners? Jes sayin…

  4. FYI 2pm today: Went to BofA w my low wage under $1000.00 work check to deposit & get $100.00 cash back 4 needed food & water 4 me & my underage kids.

    Again. BofA at ECR at Palo Alto Square not serving customers at windows & was directed 2 downtown branch on Lytton & had 2 detour because of Northbound University at ECR closed (now apparently open). Long line with many elderly, disabled, other language speakers, account holders waiting .

    1 teller working. When finally got up a teller, was informed my check would be held for up to three biz days.

    I informed them I needed cash back 2 pay rent or would get a 3 day eviction notice 2day , had to fill my car w gas & get supplies for next ten day rain As Governor has declared a State Weather Emergency.

    Instead of helping me or being kind (I have had an account at this branch for 10 years) the teller manager abused his position & made it painfully aware 2 myself & others in line he making a massive exception to help. Yet made me wait 30 minutes then informed me he had to hold the check.

    I begged him that I needed the small cash 2 prepare & safeguard my kids . He, after many more excruciating minutes demanded my SS# (he had my check and DL in their possession & behind the glass window) & reiterating verbally to me, 3 times he was making an huge exception & 4 me to never ask the bank again.

    Even informing me I would have to go Wells Fargo next , the bank issuer if I wanted to get my hard earned money.

    He got the transaction wrong and gave me the total of the check instead of the little cash I needed.

    From the time I walked into Palo Alto Square branch and Lytton street branch it took an entire 70 minutes to get cash in hand.

    This was egregious, and an absolute disgrace 2 human kind.

    I was also informed by another teller that Pacifica satellite branch yesterday forced farm working account holders 2 walk HWY1 because the smaller branch was closed to window service.

  5. @MyFeelz our labor middle management is crumbling. BofA loudly advertised auto cash back w a immediate deposit. And before Pandemic-and then all the EDD BofA fraud, is punishing poor working folk for a little of their hard earned cash. Not since 1980’s has this been so backwards! Criminalizing punishing poor account holder for a few dollars of their hard earned income!!

  6. Thank you for more details of the evacuation, that must have been quite an ordeal. How many homes were involved and how many hours were they out of their homes?
