A once-in-a-decade bomb cyclone is taking shape off the West Coast

[Yo_Mama_Been_Loggin]

A powerful “bomb cyclone” will combine with an atmospheric river to unleash over a month’s worth of rain, hurricane-force wind gusts and feet of mountain snow to parts of the Pacific Northwest and Northern California.

A storm system off the Pacific Northwest is expected to rapidly intensify on Tuesday in a phenomenon called “bombogenesis” and earn it the moniker of “bomb cyclone.” It will intensify so much so quickly that it could become a “triple-bomb,” tripling the criteria needed to be considered a bomb cyclone, the National Weather Service in San Francisco said.

Bomb cyclones are formidable and unload heavy snow and strong winds during the winter. This one could be among the most intense on record for its location, a storm that occurs only “about once every ten years,” and will generate “some of the strongest winds we have seen in several years” that churn up “very dangerous mountainous seas of 30 to 35 feet,” the National Weather Service in Medford, Oregon, said.

This bomb cyclone will work with an atmospheric river, a long plume of water vapor moving like a river through the atmosphere, to wring out heavy rainfall and significant mountain snowfall in the Pacific Northwest and Northern California beginning Tuesday. The pair will stall along the coast and hammer the area with hazardous conditions through the week and into the weekend.

1. Yeah, we prepped

Ran all the errands, did all the yard work, grabbed all the food and snacks from Costco. We're all hunkered down for the next few days. We're in North Bay, expected to get a month of rain Wed-Fri. So that'll be fun.

Movie list activate.

2. Once in a decade? Seems like we had one just a few years ago. Nt

Stunning image of the storm off the Pacific Northwest Coast...

5. Whoa Nellie 😮

That's quite a whomping headed this way...

[Cheezoholic]

7. Unrelated but I downloaded this unique conus Sat shot from last week as Raphael was weakening

I called it a "CobraJet" lol

[ultralite001]

38. Sweet...

TIA...

[FirstLight]

4. Yeah I'm a little gobsmacked right now

I knew we were expecting rain supposedly up here in the Sierras from tomorrow through Friday but now it looks like snow all the way through next Tuesday ...fuck me 😵

[ultralite001]

6. Big, juicy flakes have started falling here...

Oregon high desert...

It's eerily still out...

Awaiting the big blow... Expecting it to howl all night...

[bsiebs]

8. Well I took my umbrellas down.. so cal here...

[PeaceWave]

9. Once in a decade, eh? I clearly recall one hell of a storm just last year in the Bay Area.

[The_REAL_Ecumenist]

27. IKR? I just posted to the OP that I seem to remember the 1or 2 bomb Cyclones in winter 2023. I'm in my Sacramento

county house. I have a 25 acre farm in Paskenta Tehama county that back up against the coastal range, (Not too far from Yolla Bolly & on a clear day, we can see Shasta). Our property is parallel to Mendocino county, (Covelo & Round Valley, if you know that area). Yeah, we know from bomb cyclone and I haven't forgetten those "long ago 10 years".

[AKwannabe]

10. Wind is quite gusty at 7:15pm in N Seattle

My lights keep flickering.

Take care!!

[PeaceWave]

11. Nothing in the Bay Area yet. Where is this thing supposed to make land?

[The_REAL_Ecumenist]

28. Tomorrow. If I recall correctly, it's a storm coming from the North, so depending on where you are in the BayArea, it's

probably going to show up & show out anywhere from the early afternoon through the early evening. I'm at my Sacramanto county home , NORTH of both the City & most, if not all of Marin county. We're pretty much at the same latitude with Sonoma County. I'm ALMOST in Sutter County. Right glad TAMEETCHA...Been here since 2005.

29. About 7am in North Bay

Morning commute should be fascinating for some people.

[LittleGirl]

12. Be careful out there

I’m near Concord and they say we could get 1-6 inches of rain by Saturday. They think the storm will stay in the north of California.

[republianmushroom]

13. Didn't we have one last year ?

[PeaceWave]

14. Yes.

[republianmushroom]

16. That's what I though.

Thank you.

[Ligyron]

15. and I'm going to Tahoe from Florida for Thanksgiving?

Hopefully it's over and done by then and roads plowed since I'm not real good driving on snow and ice. Especially an 8 passenger van even if it does have all weather tires.

Best of luck to y'all in Northern California and the Pacific NW!

[Sympthsical]

30. On the plus side, resorts are opening early

We usually ski at Northstar (haven't been since pre-Covid, tho). We want to get up there this year, and I just read they're opening this weekend, which is early.

Of course, you have to actually drive through the snow to get there. So . . .

[wryter2000]

17. Hasn't started yet in Oakland

Glad I don’t live in the hills anymore.

[Hekate]

18. OMG all you guys -- stay safe! Those are terrible conditions!

[Yo_Mama_Been_Loggin]

19. Just got power back

Hoping it stays.

[Hekate]

21. Power -- and a roof over your head

[AKwannabe]

32. My friend in Woodinville says no power

And I saw a report from King 5 that North Bend lost power. I guess I will turn on the local news now since I have power.

[Silver Gaia]

20. We're hunkered down and ready as we can be!

The one we had on New Year's Eve a couple years ago ripped our roof up so badly it had to be replaced. So... at least the roof is new. Hope it holds up!

The winds don't look so bad in the forecast for our area, and that was the worst part of the other one. But they didn't predict what we actually got that time, either, so who knows?

Whatever we get, we are as ready as we can be.

[Hassler]

22. The wind was howling pretty strong in Eugene about 5 pm

[fierywoman]

23. Redmond/Grasslawn WA here -- a tree fell down lengthwise down the street (tiny street; actually a "CT' --)

just got a text from the neighbors that they scheduled an 8 am "chainsaw party" for the street for tomorrow morning -- I LOVE MY PACNW NEIGHBORS !!!'

[pfitz59]

24. The lights are flickering

and the power went out for a couple of minutes. My neighborhood has all underground utilities. Thankfully, as tree limbs are snapping all around. We are set. Went to the store yesterday and stocked up.

[The_REAL_Ecumenist]

25. Well, if this bomb cyclone has been "once in a Decade", Apparently, 10 years have passed since the 1 or 2 BOMB CYCLONES

we had in 2023, (I'm right outside of the Capital of the GOLDEN STATE). Medford OR is about approximately 200 miles as the crow flies from my farm in Paskenta.

[Sympthsical]

31. I think because it's a combination of factors

Not just a regular bomb cyclone, but one combining with an atmospheric river to create a "perfect storm" of nonsense for us.

[The_REAL_Ecumenist]

33. That's what hit us here in NorCal. What region of the country are you in ? EOM

[Sympthsical]

34. I live in Solano County near Napa

We are fully battened down now.

[The_REAL_Ecumenist]

35. Well, hello neighbor. We went through 2 of those cold cyclones inJan '23, I believe, if I can recall correctly.

But, leave us not forget that there's no such thing as CLIMATE CHANGE.

[The_REAL_Ecumenist]

37. I'm cooking up EASILY warmed soups and stews. The only thing I'm REALLY worried about are the 4 redwoods I have in my

garden around my house. ONE of the tallest trees almost bent to the roof, (I have a 2 story TRUE townhome- we share no walls but we close as hell to the neighbours to the north and south. I stayed up all night monitoring that tree. Of course, it floods here but I'll monitor Dry Creek, which is pretty much an Arroyo which can go from bone dry to a raging water way in less than 24 hours. Are you anywhere near the Napa River?

[The_REAL_Ecumenist]

36. That bomb cyclone his us as PART of that particular Atmospheric River. It flooded like NOBODY'S business all around us.

My Sacramento home is in the North Natomas area. The Sacramento is about 3.5-5.5 miles from me. If you've ever travelled out of Sacramento International, you were about 2.5-4 miles to the west southwest.

[jalan48]

26. Lots of rain (for us) and wind in So Oregon.
