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.

Bomb Cyclone brings blizzard to Midwest

Bomb Cyclone

Luke 21:25-26 “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, people fainting with fear and with foreboding of what is coming on the world. For the powers of the heavens will be shaken.

Important Takeaways:

  • Potential Pre-Christmas Bomb Cyclone Could Bring Blizzard Conditions In Midwest, High Winds In East
  • A major storm will track through the Midwest, Northeast and South through the end of the week.
  • The heaviest snow will target the Great Lakes, with over a foot possible for some.
  • High winds capable of tree damage and power outages could blast much of the Plains, Midwest and East
  • Severe travel impact because of snow, wind and cold is expected from through at least Friday or Saturday.
  • As a rule of thumb, meteorologists refer to a strengthening low as “bombing out” or undergoing bombogenesis if its minimum surface pressure drops by at least 24 millibars in 24 hours or less, though that criteria also depends on a storm’s latitude.
  • Meteorologists frequently discuss pressure in terms of millibars, rather than inches of mercury.
  • The reason this all matters beyond just a weather geeky statistic is the lower the pressure in a storm, the more intense it is. And the greater difference in pressure over an area, the stronger the winds.

Important Takeaways:

  • Winter Storm Watches issued for Boston, New York, Philadelphia ahead of powerful weekend nor’easter
  • A powerful nor’easter will develop into a “bomb cyclone” off the East Coast
  • Expected to intensify into a bomb cyclone, a term used to describe a low-pressure system that undergoes “bombogenesis” – defined as a rapid pressure drop of at least 24 millibars in 24 hours or less – indicative of a very intense storm.
  • Heavy snow, high winds and coastal flooding are expected
  • You’re advised to avoid all unnecessary travel across this region.
  • A large portion of the Northeast coast could face a significant threat of coastal flooding, high surf and beach erosion. Astronomical tides will already be running high this weekend as we approach a new moon, which will only make these threats worse.

Blizzard clobbers Plains and Midwest after blanketing the U.S. Rockies

By Keith Coffman

DENVER (Reuters) – A powerful blizzard slammed the U.S. Plains and Midwest on Thursday with heavy snow and fierce winds that caused power outages and closed highways while raising fears of more flooding in the Midwest after a deluge last month.

The system was dumping more than a foot (0.3 m) of heavy snow and winds were gusting up to 65 miles (105 km) per hour from northeast Colorado north to northern Wisconsin, the National Weather Service said in multiple advisories.

Whiteout conditions on roadways were making “travel extremely dangerous,” according to the weather service. Blizzard and winter storm warnings would remain in effect across the region through Friday morning, it said.

“Conditions will continue to deteriorate the rest of the afternoon and overnight,” said Dan Effertz, a NWS meteorologist in Minnesota. “This is a very potent storm.”

Local media reported dozens of crashes and cars in ditches as several major highways and roads were shut down in parts of the U.S. Plains and Midwest. Some counties issued “no travel” advisories, warning drivers to stay off the roads.

“Blizzard, day two. Not even the pack of sled dogs can handle these roads,” said Minnesota crime novelist Anthony Neil Smith on Twitter.

More than 30,000 homes and businesses were without power in Minnesota, 14,200 in Iowa and 22,700 in Michigan by midday on Thursday, according to PowerOutages.us, a website that tracks power outages.

The storm beginning on Wednesday has already dumped more than 2 feet of snow on parts of South Dakota and more than about a foot of snow in communities in Wyoming, Montana and Colorado.

The storm caused officials to close schools and governmental offices in dozens of communities.

In addition to snow, the storm was bombarding the region with rain, sleet, freezing rain and thunderstorms.

“You can probably even throw in the kitchen sink at this point,” the weather service said in a Tweet.

The blizzard, dubbed a “bomb cyclone” because of its rapidly intensifying funnel shape, is the second one to hit the region over the past month.

In March, another “bomb cyclone” triggered heavy rain over the region and combined with melting snow to cause flooding along the Missouri River and its tributaries. Damages and losses to property, cattle and crops in Nebraska and Iowa alone were estimated at more than $3 billion.

Officials in Nebraska on Thursday were cautiously watching the forecast and river levels to the north, said Jodie Fawl, a spokeswoman for the Nebraska Emergency Management Agency.

“We are waiting to see what happens when the snow melts,” she said, noting that warm temperatures since then have thawed the ground and could result in less flooding. “We are just going to have to wait and see.”

Despite the severe weather, crew members at Denver International Airport worked through the night to remove snow from runways, and only about 180 flights were canceled on Thursday morning, down from more than 700 a day earlier, according to FlightAware.come, a flight tracking service, and airport officials.
