How a powerful bomb cyclone ravaged the Northwest

Seattle Times staff reporters
This storm was off the charts.
The bomb cyclone emerged from the middle of the Pacific
Ocean and swirled with such intensity off Washington’s
coast that it ravaged the region Tuesday night, ripping
down trees, toppling power lines and killing at least
two.
Each storm like this is unique — with its own
personality, said Lynn McMurdie, a professor of
atmospheric sciences at the University of Washington.
“And this one has a lot of personality,” she said.

What to expect
How a powerful bomb cyclone ravaged the Northwest
Pressure dropped 27 millibars in six hours, about four
times faster than the rate meteorologists use to label
storms as bomb cyclones. It dropped so far and so fast
that, under one method of analysis, it landed in a
category reserved for the strongest of its kind: A
“super explosive cyclone.”
Bomb cyclones are common enough, but rarely form as far
south as this one did and gather so much strength so
quickly, said Jason Ahsenmacher, lead meteorologist for
the National Weather Service in Fairbanks, Alaska.
As far back as the records go, a cyclone this strong
hasn’t formed before in this part of the world at this
time of year, Ahsenmacher said. It belongs to an upper
echelon of low-pressure systems.

it's working south and it looks like it's going to start
hitting us tomorrow...have rain on the forecast every
day until thanksgiving.
Hatches battened. Although i'm hoping it's lost a lot of
that energy by the time it gets to us.
I don't see wind warnings here, at least (southern
Sierras).

yikes...that's a lot of rain. Hoping you are safe.
This thing is hitting this morning, but so far just
drizzle and light rain. 50F out, and too warm to snow.
But, you know, it's just started here.
NWS has us down for rain until next wednesday.

Historic storm breaks 1,000-year rainfall record in parts of Bay Area
By Sam Mauhay-Moore, Trending News Reporter Nov 23, 2024
This week’s atmospheric river storm smashed some heavy rainfall records in parts of the Bay Area, especially the North Bay, before mostly petering out by Saturday morning. Downtown Santa Rosa received 12.47 inches of rain in a three-day period, the National Weather Service said on social media, breaking a thousand-year record.
As of Saturday morning, the Santa Rosa Airport has seen 386% of its normal rainfall amounts since Oct. 1, National Weather Service meteorologist Ryan Walbrun told SFGATE.
“They’re at 15.48 inches, and they should be at 4.01 for a normal year,” Walbrun said.
The bomb cyclone storm system first battered the Pacific Northwest this week, killing two people in Seattle and causing power outages throughout the region beginning Tuesday before arriving in Northern California.
Flash floods caused landslides and road closures across the Bay Area on Friday, with some roads still being closed due to flooding in San Francisco, Oakland, Napa, San Jose and parts of Contra Costa county. A massive 15-foot pothole closed a southbound lane of Highway 101 in San Francisco early Saturday morning. All lanes appear to be open as of Saturday afternoon.
Flood warnings remain in effect in areas along the Russian River near Guerneville, which saw flood impacts that submerged some vehicles and buildings on Friday.
Rescue crews in Guerneville recovered a body inside a vehicle bobbing in floodwaters around 11:30 a.m. Saturday, according to Rob Dillion, a Sonoma County sheriff's deputy and spokesperson. The deceased was presumed to be a victim of the storm, but an autopsy had not yet been conducted.
The region is still experiencing some scattered showers, with a chance of “steady precipitation” for Sunday night thr

Like you, no rain yesterday and we saw the sun. This
morning, the light rain is back. We're good in the so.
sierras at this point. The light rain is nice. More on
the way I hear, though.
Still warm here (relatively)52F. No snow with the
atmospheric river. It's too warm. The ski resorts are
probably cussing.
