A massive storm system is approaching the San Francisco Bay Area in California, bringing with it the threat of heavy rain, high winds, and feet of snow in the Sierra region.
Rain is expected to be so heavy the NWS says it’s possible that human lives will be lost during the storm.
Known as the Pineapple Express, the storm is expected to rapidly intensify into what meteorologists refer to as a ‘bomb cyclone’ over the northern Pacific Ocean bringing an atmospheric river of moisture into the state.
This will be the third storm in California to bring an atmospheric river since the end of December, including one on New Year’s Eve that caused severe flooding and debris flows.
It is expected to hit the Pacific Northwest on Wednesday and cause devastation and major power outages.
A major storm that will rapidly intensify and become a bomb cyclone off the coast of California will slam into the Golden State, unleashing the risk for life-threatening flooding, damaging winds and power outages from Wednesday into Thursday, AccuWeather meteorologists warn.
The storm will arrive just days after the deadly flooding and heavy snow that developed in the state over the holiday weekend, threatening travelers and causing hundreds of thousands of power outages.
An atmospheric river, or massive plume of moisture originating from the tropical Pacific Ocean some 2,500 miles away, will fuel the heavy precipitation. Such a weather setup can lead to excessive rainfall and flooding, as well as a thump of snow that can shut down travel where the atmosphere is cold enough. In this particular case, the event can be classified as a Pineapple Express, since the plume of moisture will extend from near Hawaii.
“There is a significant risk for flash flooding, and people should watch for and avoid rapidly rising water which can quickly become life-threatening,” AccuWeather Chief Meteorologist Jon Porter said, adding that flooding may result in street and highway closures. “This will be a dangerous and high-impact storm for California, capable of producing life-threatening conditions and significant disruption which may last several days.”
Mudslides are among the dangers that can persist for several days even after the rain ends, Porter explained.
“Not only will this storm be intense tapping into a substantial atmospheric river, but it is also arriving just days after the previous storm brought heavy rainfall and created significant flooding, increasing the impacts and risks that can occur,” he said.
The rapid intensification of the storm, in a process known as bombogenesis, will add to the dangers it poses, including strong winds on top of the extreme precipitation. When the barometric pressure falls at least 0.71 of an inch (24 millibars) in 24 hours, a storm has undergone bombogenesis, and meteorologists will often refer to this type of strengthening system as a bomb cyclone.
“The atmospheric river will initially be directed into Northern California on Wednesday, Central California Wednesday evening and then Southern California later Wednesday night into early Thursday,” AccuWeather Senior Meteorologist Brett Anderson said. “Rainfall rates may exceed 2 inches per hour in some areas, especially over higher terrain.”
Multiple areas face excessive rainfall on the order of 4-8 inches of rain, and up to 12 inches. Rainfall of this magnitude on top of the several inches of rain that fell on New Year’s Eve could result in a dangerous flash flood and mudslide situation in a number of communities of the Golden State.
In advance of potential flooding across the state, the California Department of Water Resources stated Tuesday that the organization has prepositioned flood fight materials and equipment at 38 different locations, and have deployed levee inspectors before the rainfall.
Areas at greatest risk for upwards of 4 inches of rain from the new storm include coastal areas of California, just north of San Francisco, as well as areas just south of San Francisco to the mountains just north of Los Angeles, AccuWeather meteorologists say. An evacuation advisory was issued Tuesday for southern coastal areas of San Mateo County, just south of San Francisco, while a mandatory evacuation order was issued for Watsonville, approximately 50 miles south of San Jose.
Another pocket where 4 or more inches of rain is likely to pour down is the west-facing lower slopes of the Sierra Nevada just east of Sacramento to just east of Redding, California.
The cities of San Francisco, Sacramento and Los Angeles will still receive heavy enough rain from the storm to lead to flash flooding, forecasters say. San Francisco is likely to pick up 2-4 inches of rain from the storm with 1.50 -3 inches on the way for Sacramento and Los Angeles. Much of that rain may fall within a 12-hour window or less with quick runoff collecting on area streets and highways.
“Motorists traveling through the region may encounter washed-out secondary roadways and may have to take detours,” Anderson said.
Another significant problem from this storm will be caused by strong winds, which can approach hurricane force (74 mph or greater) in some locations. The high winds will be created as the barometric pressure plummets in the storm and causes air to rush in toward the system’s center.
The force of the wind can cause poorly rooted trees in saturated soil to topple over. Where utility lines are in the way, power outages will result. Hundreds of thousands of utility customers could experience power outages from the storm.
“Residents should make preparations for this storm by filling up their cars with gas, having enough gas to power generators, and stocking up on non-perishable food items in case there is an extended loss of power,” Anderson said.
As tree limbs break or trees come crashing down, people in stopped vehicles and pedestrians beneath can be seriously injured.
“Travel during the height of this storm is strongly discouraged,” Anderson said.
“Snow levels in the Sierra Nevada are expected to be mostly above pass level on Wednesday but then begin to lower Wednesday night and Thursday with several feet of snow, especially above 7,000 feet,” Anderson said. “Travel through the higher passes of the Sierra Nevada Wednesday night into Thursday may become very difficult due to high snowfall rates, near-zero visibility and strong winds.”
There is the potential for road closures along I-80 due to heavy snowfall. The highway in the Sierra Nevada was closed for many hours over the New Year’s weekend as snow piled up fast and stalled vehicles.
Snow levels are likely to remain above Southern California passes, but snow could fall for a time at Siskiyou Summit along I-5 near the Oregon/Northern California border.
The atmospheric river that targeted Northern and Central California Saturday produced the second-highest daily rainfall in the history of Downtown San Francisco. The 5.46 inches of rain that fell on the city was second only to the 5.54 inches of rain that fell on Nov. 5, 1994. Records date back to 1849.
The same setup brought a staggering hourly snowfall rate of 7.5 inches per hour Saturday afternoon at the Central Sierra Snow Lab and deposited several feet of snow on the high country of the Sierra Nevada in 12-24 hours.
Without question, the barrage of storms will help tremendously with the long-term drought in California and many other parts of the West. Some reservoir levels may surge to full capacity before the storm train eases down later in the month.
Many additional storms will roll ashore from the Pacific through the middle of January. The storms may be as little as 12 hours apart at times.
“Residents of the West Coast should continue to frequently check AccuWeather as additional storms are expected to parade into the West Coast through January bringing additional episodes of damaging winds, heavy rainfall and heavy snow in the mountains,” Porter said.
Each of these storms will have the potential to produce rounds of flooding rain at low elevations and heavy snow in the high country, AccuWeather meteorologists say. However, since the overall storm track is likely to shift farther to the north along the West Coast, many of the storms may avoid bringing much rain to Southern California. Storm-related problems are likely to increase in Oregon and Washington. [Accuweather]
Such is life. anyone familiar with biblical curses, knows droughts and flooding are part of it. First, loss of wealth, and Kali’s been hemorrhaging wealth for years. The curse began in 2009 when liberals took the state. Don’t expect things to get better till they’re removed and replaced with non-nazis, conservatives.
Wouldn’t explain why the NASA hotspot (rich liars from “outer space”) peninsula has arctic freezes and so many destructive hurricanes. It’s not just liberals, Republicans (including “real non rhino ones”) are all equally as corrupt and selected by the CFR/UN to usher in Ordo Ab Chao under the guise of serving the citizens (slaves in reality).
Because of the increasing Earth Wobble due to the approach of Nibiru.
You either choose satan or satan-lite. If you choose neither, then that is a vote for satan. Of course, you are too stupid to realize that, anonymous ??.
California will go to ocean but these are prelude to world war 3 and mass population reductions.
Medical Martial Law in California and USA if you do not have bogus COVID 19 shots you will not be treated for surgeries and they keep delaying right diagnosis until you beg for kill shots… 1oo Million people in USA has no shots and another 55 Millions only had one shots.. They keep closing down
and mass unemployment will be high , so you beg them for shots.. Welcome to full Martial Law in USA
and world wide .. before west coast of USA goes to ocean the, floods and hurricanes , after each others paves away for final shake down down by HAARP? Russia has send massive atomic Zicron
Missiles in to transatlantic Ocean and UK loves WW3 ….
Some people don’t need doctors. If you pray to Christ, then he can heal you. I have seen it happen right before my very eyes. To myself, and my animals.
I doubt he will let the reservoirs fill because they are worried about the West Coast EQ events. I think this is the real reason they drained them. Fish story just cover.
Interesting hypothesis. Sounds plausible.
This weather is normal for California. There are historically heavy rains and mudslides during Winter. In fact, there was a severe event back in 1971 or so. Our house got flooded. We had a runoff channel in the side yard up in the mountains. Water runoff hit a chainlink fence and pushed debris up on the fence. Made a dam in effect. Water surged over our retaining wall, and backed up into our back patio. Flooded the basement and into our house. Big mess. Insurance didn’t cover it either. That was before flood insurance coverages.
I remember another time where it rained a entire week nonstop back in the late 1980’s too. Storm channels backed up and roads were like rivers. Mudslides killed people then too. Fires had burned off the ground cover, so hillsides got saturated, then mudslides occured.
Why is there zero reporting on the water table and drought psyop?
Here in KY we call this …Rain.
This has happened time and time again but everybody thinks Climate History started on their Birthday. Hell +- 12,700 yrs ago the Sun decided to put out massive amounts of energy and the Northern hemisphere Ice Cap melted…very damn quickly…think Noah, Epic of Gilgamesh and several others from all over the World.
The Sun had been at Low Output before this time as it is doing now and that is called a Solar Minima. The Eddy Minimum that we are in for the next +- 3-6 Decades won’t be as cold as the Ice Age BUT…you are going to want that Heat everybody hates these days.
Less deaths in hot times than cold times…think!
It’s called a curse. When liberals took over in 2009, the drought started. Droughts and floods are part of the curses the Lord gave to Moses. First, the money goes. Cali’s been hemorrhaging wealth since 2009.
Well, looking on the bright side I’d say Gabbin Nuisance has a lot of water to store up so he can release it back into the ocean to save more fish … I mean he could store it up to stop the drought ravaged farms in Commiefornia… but why would he do such a thing ?
If Cali would build MORE reservoirs ya’ll would have water in dry times.
But greenies love troubles instead of cures.
I moved when Pete Wilson’s prop 187 was overturned. Whole state was full of buttclowns and fckery. My best friend from youth baseball days still lives there, but in a nice area since he has big money. If you don’t make big money, that state is hosed. Big money gives somebody the ability to insulate themselves from shitholers.
