A transient supercell developed SE of #Victoria this evening around 7:17pm. A very rare treat over this part of the world. #BCstorm #BCwx @tylerhamilton.bsky.social @yvrwxwatcher.bsky.social

#Hurricane Season in the Atlantic ends on Saturday. The first season above 1.5 degrees for the whole year. How does it compare?

Unreal paths of damaging winds, east of Everett, WA near Forest Glade, WA #wawx #bombcylone #weather #mountainwave #wind

this place feels fresh. I love it so far! And yes...so much weather...and no more hate!

Massive & intense low continues to spin off our coast spanning from the AB/SK border to out in the #Pacific & AK to Central CA!
Across SW #BC, 95,953 customers w/o power this AM w/ Wind Warnings still covering many parts of #VanIsle; several roads closed w/ travel not recommended.

What it's like to watch a plane land during a bomb cyclone. 💨✈️ #wawx

942mb bomb cyclone!! Likely the lowest pressure ever recorded in this area of the Pacific Ocean #wawx

There she blows!! #wawx #BCwx

This is what it's like on Hwy 4 in Cathedral Grove just before the hwy was closed. The person taking the video tells me "It was scary. 5-7 ft branches raining down. Trees swaying, wind howling. I felt like a sitting duck waiting for a tree to fall." #bcstorm @CHEK_News

The barometric pressure at buoy 46005, 300mi/480km off the Washington coast near Aberdeen down to 954hPa!!
Looks at that steep drop in pressure as a result of the rapidly intensifying low in the NE Pacific

For anyone that’s curious, here’s a satellite picture of this storm - it’s massive, and quite picturesque from that height! The state borders are in light blue - so the center of the circulation is due west of Long Beach. #wawx

Amazing. This feature in BL cloud caught my attention! Upper trough / trop-fold punching down very low.

The model guidance suggests a significant windstorm is likely for all of Vancouver Island, potentially affecting 200,000+ customers. Unlike typical wind events that last 6 to 8 hours, this storm is expected to persist for twice that duration and not be isolated. #BCStorm

Bomb cyclone stuns in new photos.

Pressure falls at buoy 46005 are just incredible #wawx #bombcyclone

Bombogenesis at the latitude of New York City (40.7°N) is ~18mb/24hrs. This storm just eclipsed that in one hour... #wawx #bombogenesis #bombcyclone

Not every day you see a sub-950 hPa low form this close to the WA/OR coast. In fact, it’s entirely outside of the 30-year climatology for mid-November in that particular location.

Structurally, this is the most fascinating storm I've seen here. The strong east winds are a bonus addition to the oddity (albeit not a welcome one. Half my fir trees will be raining twigs and branches onto my house and truck). On the plus side, most deciduous trees are nearly leafless now. #wawx

Fun fact: the criteria for bombogenesis is dependent on latitude! At ~48°N, the threshold is roughly a 22mb pressure drop in 24hrs. This storm will likely 3x that rate and then some! It doesn't look impressive on satellite quite yet, but this is a true instance of "just give it a few hours." #wawx

I believe that would be triple bombogenesis

GFS has -62mb drop in 24 hours. After adjustment from 45°N to 60°N (which is used for the -24 mb / 24 hr rule) that's a -75.6mb drop

B.C. bomb cyclone to create the world’s largest wave pool - The Weather Network The swells generated by the next B.C. storm will propagate thousands of kilometres, reaching as far as Hawaii and the western beaches of Mexico’s Baja Peninsula. Talk about impact.

Monstrous waves will be generated by the bomb cyclone. Like as big as..
•A 6-story building
•4 adult giraffes stacked tall
•10 African elephants
•3 Tyrannosaurus rex dinosaurs

A map of the United States showing how many days it has been since the most recent hurricane force wind warning. Medford and Portland have gone 2953 days, Maine has gone 311 days and further south on the Atlantic Coast is 2000+.

NWS Medford has issued their first hurricane force wind warning since October 2016.

Watching the wind potential for Tuesday evening — amplified mountain waves in favored spots on the eastside are a major concern. Sea-Tac might push 50 mph gusts as well.

GFS forecast model showing a strong low pressure storm off the West Coast on Tuesday.

Latest GFS has 950mb low but it’s the bunching of black lines (pressure isobars) that tell the story. Incredible near the low but also look at them bunching close together over the Cascades. #wawx

*Not a Forecast*
Ain’t one for posting mdls but when a 933mb low shows up, well, you gotta share.
For ref Cat5 Hurricane Beryl bottomed out @ 934mb & had winds to 165 mph (270 km/h).
While not likely to reach that, it is gonna be an impactful low - how much? we’ll see!

Thank you. 🍻
