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.
