Over the past few years, weather patterns all over the planet have been going completely insane, and now it is happening again.
It is very rare for an atmospheric river and a “bomb cyclone” to occur simultaneously, but that is precisely what we are witnessing…
The arrival of an atmospheric river – a long, narrow band of heavy moisture from the tropics – coincides with conditions in the Pacific where a polar air mass collides with a tropical air mass, causing the atmospheric pressure to drop quickly. Meteorologists call such low-pressure systems a bomb cyclogenesis, bombogenesis, or a bomb cyclone, which intensifies the storm and increases its winds.
It would be bad enough to be facing an atmospheric river and a “bomb cyclone” at the same time, but it turns out that both of them are also immensely powerful.
According to meteorologist Ryan Maue, this is a “Category 5 atmospheric river”, and the central pressure of the “bomb cyclone” will drop so low that it will be “similar” to a Category 4 hurricane…
A massive “bomb cyclone” is set to explode off the U.S. West Coast with hurricane force winds, flooding rains, and enormous mountain snow from Category 5 atmospheric river.
Central pressure will fall almost 70 mb / 24 hours reaching 942 mb — similar to Category 4 hurricane.
Ryan Maue is a very highly respected meteorologist, and I have no reason to doubt what he is saying.
He is also telling us that approximately 20 trillion gallons of moisture will be dumped on the U.S. over the next week…
Just in the next 7-days from the “climate fueled” atmospheric river and mega “bomb cyclone”
8 Trillion gallons of precipitation will fall on California
5T on Oregon and 3T on Washington + 2.5T on IdahoPushing 20 Trillion gallons from this extreme event.
This has the potential to be a historic disaster.
According to Accuweather, it is being projected that the central pressure of the “bomb cyclone” will “crash from 29.53 inches (1000 mb) to at least 28.05 inches (950 mb) in 24 hours”…
We have seen “bomb cyclones” before.
But I have never heard of a storm’s central pressure falling so fast that it actually doubles the criteria for a bomb cyclone.
We are being told that the hardest hit areas along the west coast will be “between the San Francisco Bay area and Eureka, California”…
The heaviest impacts, classified by the University of California, San Diego as “extreme,” will be between the San Francisco Bay area and Eureka, California, according to WeatherNation. Strong impacts from the storm are expected as far north as central Oregon and as far south as Salinas, California. These include high winds, heavy rain, and the potential for flash flooding.
But that doesn’t mean that you will be able to relax if you live outside of the target zone.
For example, a blizzard warning has been issued for the Cascade mountains outside of Seattle…
The National Weather Service in Seattle issued a blizzard warning for the Cascade mountain passes starting Tuesday, cautioning residents and travelers of hazardous conditions set to begin on Tuesday afternoon.
The warning takes effect from 4 p.m. Tuesday until 10 a.m. Wednesday for elevations above 2,500 feet, and includes areas such as Hamilton, Concrete, Lyman, Morton and Darrington.
An urgent weather warning has been issued for three West Coast states after a bomb cyclone is expected to unleash hurricane conditions in the region.
The National Weather Service (NWS) alerted residents in northern California, Oregonand Washington to potential hurricane-force winds, catastrophic flooding and feet of high-elevation snowfall this week.
Meteorologist Ryan Maue said that the central pressure of this bomb cyclone will fall almost 70 millibars in 24 hours, reaching pressure levels similar to that of a Category 4 hurricane.
This super-charged storm will bring wind gusts of up to 70 miles per hour, and pull a Category 5 atmospheric river onto land that will dump up to 20 inches of rain in certain areas.
An atmospheric river is a long and narrow region of the atmosphere that carries warmth and moisture from the tropics toward Earth's poles. A Category 5 is exceptionally hazardous, bringing intense storm impacts to land.
Storm impacts are expected to begin Tuesday afternoon and persist through the week, possibly stretching into the weekend.
Americans living in these areas are advised to find shelter in an interior room on the lowest floor of a sturdy building and avoid cars and mobile homes.
The NWS predicted that northern California and Southwest Oregon will see the highest rainfall totals, potentially resulting in flooding, rockslides and mudslides.
As these storm systems move toward the West Coast, Washington, Oregon and California can expect at least six inches of rain, with over 20 inches possible in the mountains.
The stream of moisture funneling into the mountains could also drop feet of snow from the higher elevations of the Cascades southward into the Siskiyou Mountains of Northern California. This may impact travel in some passes.
High winds should kick up on Tuesday and persist into early Wednesday, with coastal parts of Northern California, Oregon and Washington potentially weathering gusts over 60 or 70 mph. Power outages and downed trees are expected.
Bomb cyclones form when a midlatitude storm rapidly intensifies over a 24 hour period.
Intensification essentially means a drop in pressure, and storms need to drop at least 24 millibars within a 24-hour period to be considered a bomb cyclone.
It is rare for a storm to lose 70 millibars of pressure this quickly.
By comparison, Hurricane Milton - which rapidly strengthened from a Category 1 hurricane to a Category 5 - lost 84 millibars of pressure in 24 hours.
A bomb cyclone is the west coast's version of a Nor'easter. Two notables March 1962 & '93.
