I have been watching the predicted development and path of a small low center and the trend of the runs has been ominous.
The predicted path is nearly optimal for producing strong winds from Seattle to Olympia, with a near certainty of power outages. So if you live in this region...get ready. Quite a blow is now only 6-15 hr away.
Here is the situation.
By 4 AM Thursday morning, a 981 hPa low center will be positioned over the NE side of the Olympics
Three hours later it will move over NW Washington, with an intense pressure gradient over southern Puget Sound. This means very strong winds there.
The low then moves northeastward into southern BC. This is a near-optimal path for strong winds over Puget Sound.
Now let me show you the predicted wind gusts. At 7 AM, there are gusts of 40 kt and more over the south Sound.
One hour later things are getting crazy in the Strait of Juan de Fuca, and over Seattle and the south Sound (blue colors).
Five hours later, Puget Sound winds have calmed, but intense downslope winds have developed on the eastern slopes of the Cascades.
Seattle WindWatch shows the multiple predictions of strong winds over Seattle.
Bottom line: if you are in the vulnerable areas, prepare. Charge your electronics, etc.
Thank you for the late night update Cliff. This looks very impressive on water vapor imagery as it's intensifying now. The bent back occlusion looks beastly. I wonder if the NWS will upgrade to High Wind Warning for South Sound. ICON model gets it down to 977. This will.be fun!!
ReplyDeleteLooks like kitsap will be spard Bremerton area
ReplyDeleteThis is what the CBC says
ReplyDelete"The storm affecting B.C.'s coast is the second in a series of three weather systems hitting the province this week.
Kelly Greene, the province's emergency management minister, said the storms are much stronger than they used to be, due to climate change."
But offers no evidence whatsoever.
