Another Bomb Cyclone and Atmospheric River batter the Pacific Coast

Bomb Cyclone

Important Takeaways:

  • A second powerful bomb cyclone and atmospheric river system is battering the Pacific Coast states, bringing more severe weather to regions still reeling from Tuesday’s devastating storm that left hundreds of thousands without power and claimed one life in Washington state.
  • As of Friday morning, approximately 180,000 Washington residents remained without electricity, while California reports over 15,000 customers experiencing outages, according to poweroutage.us.
  • So severe is the issue in Washington that Puget Sound Energy (PSE), the state’s largest utility provider, issued a letter to customers on X, formerly Twitter, on Thursday evening.
  • “To our customers without power: we know you are frustrated,” the letter said. “The system was so strong that it was comparable to a hurricane and did unprecedented damage to our high-voltage transmission systems—the poles and wires that carry electricity from where it is produced to the communities we serve.”
  • The company plans to have the majority of customers back online by Saturday at noon.
  • The National Weather Service (NWS) has issued severe warnings about life-threatening flooding conditions, particularly in Northern California.
  • The forecast includes between 3-5 inches of additional rainfall in coastal areas, with 4-10 inches possible in the northern Sierra Nevada.
  • From Northern California to southwestern Oregon, cumulative rainfall is expected to reach 8-12 inches, with potential for up to 20 inches in some locations, according to AccuWeather.
  • The consecutive storms are creating multiple hazards across the region, including a high risk of dangerous flash flooding, potential for mud slides and landslides, and significant erosion concerns.

West Coast warning: Atmospheric River and a Bomb Cyclone look to bring high winds and tons of rain between the Bay area and Eureka, California

Important Takeaways:

  • What happens when an atmospheric river and a “bomb cyclone” happen at the same time? Unfortunately, millions of people living on the west coast are about to find out.  Extremely high winds, massive amounts of rain, and blizzard conditions in the mountains are being forecast for the days ahead, but nobody is quite sure exactly how this extremely unusual weather event is going to play out.
  • 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…
  • 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”…
    • The storm will strengthen so fast that it will fit into a special category of weather terminology known as a bomb cyclone. A storm, or cyclone, is essentially a giant spinning vacuum in the atmosphere. When a storm’s central pressure drops 0.71 of an inch of mercury inches (24 millibars) or more in 24 hours or less, it is considered to be a bomb cyclone.
    • “This storm’s central pressure is forecast to crash from 29.53 inches (1000 mb) to at least 28.05 inches (950 mb) in 24 hours, which is double the criteria for a bomb cyclone,” AccuWeather Senior Meteorologist Heather Zehr said.
  • We are being told that the hardest hit areas along the west coast will be “between the San Francisco Bay area and Eureka, California”…
  • A blizzard warning has been issued for the Cascade mountains outside of Seattle…
  • I think that this storm has the potential to do an enormous amount of economic damage.

Southern Sierra Nevada hits record Snowpack as another Atmospheric River makes its way to California

Sierra Nevada Snowpack

Luke 21:25 ““And there will be signs in sun and moon and stars, and on the earth distress of nations in perplexity because of the roaring of the sea and the waves

Important Takeaways:

  • California Hits Record Snowpack Depth in Southern Sierra Nevada
  • The total snowpack this winter for California’s southern Sierra Nevada mountain range has hit 286% of normal — the highest since records began.
  • The Los Angeles Times noted:
    • As of Friday, the snowpack in the southern Sierra Nevada was at 286% of normal — the highest figure ever, easily eclipsing the region’s benchmark of 263% set in 1969.
    • Statewide, the snowpack is at 228% of normal, hovering near the record level set in the April 1 survey of 1952, 237% of average. The level during the annual April 1 snow survey in 1983 was 227%.
  • According to the University of California Berkeley Central Sierra Snow Lab, the 2022-2023 has been the second-snowiest on record — and it could surpass the record mark set in 1952, with more snow on the way in an upcoming “atmospheric river” that will be the season’s 13th.

  • California Endures 12th Atmospheric River as Spring Begins
  • LOS ANGELES, California — Residents of the Golden State spent the first full day of spring dealing with the twelfth “atmospheric river” storm of the season, as heavy rains pounded cities and snow fell on the mountains.
  • The San Francisco Chronicle noted that heavy winds accompanied the storm, reaching up to 88 miles per hour. The winds blew out 20 windows in the Salesforce Tower and at least one window in Millennium Tower nearby.
  • The National Oceanic and Atmospheric Administration (NOAA) posted a video loop of the storm, which also developed two “eyes” that came ashore — a rare weather phenomenon known as the Fujiwhara effect.

Soaked California hit by another Atmospheric River causing 16 major rivers to flood

Luke 21:25 ““And there will be signs in sun and moon and stars, and on the earth distress of nations in perplexity because of the roaring of the sea and the waves

Important Takeaways:

  • The latest storm put nearly 27,000 people under evacuation orders due to flooding and landslide risks and caused 16 major rivers in the state to overflow.
  • On the Pajaro River a broken levee caused by a similar storm on Friday was again overwhelmed, flooding farms, roads and submerging the entire town of Pajaro and forcing thousands of residents to flee.
  • Damaging winds with speeds of 70 mph blew out windows, and there were numerous reports of falling trees.
  • Power outages hit more than 330,000 utility customers in northern and central areas, according to poweroutage.us, which tracks outages nationwide.
  • Atmospheric rivers can carry up to 15 times the volume of the Mississippi River, according to the National Oceanic and Atmospheric Administration.
  • In 2019, an atmospheric river nicknamed the ‘Pineapple Express’ hit California. The water vapor from near Hawaii brought rain, triggered mudslides and forced motorists to swim for their lives.
  • In 2021, an atmospheric river dumped a month’s worth of rain on British Columbia in two days, prompting fatal floods and landslides, devastating communities and severing access to Canada’s largest port.
