Get ready for a 2nd round of wind this afternoon; it looks stronger than what we just went through yesterday.
- Strong wind develops by 4pm at the Coastline and arrives between 4-6pm here in the western valleys.
- Peak gusts 70-80 mph on the coast
- Peak gusts 45-55 mph here in the valleys, PDX gusted to 43 yesterday.
- Wind will gradually die down after 8pm.
- More rain, but no more than 1.25″ here in the metro area
A nice break the last 12 hours since we are inbetween weather systems. Now the remnants of Typhoon Pabuk have made it all the way across the Pacific and what’s left will spin up into a powerful low pressure center the next 12 hours. Morning models are coming out and showing the low “bombing” down to around 970 millibars and landing somewhere between central Vancouver Island and the NW tip of Washington. Truly historic for September 29th! Here’s the 12z NAM-MM5 model:
and our 12z RPM:
And the 12z WRF-GFS for 7pm today:
compare that with the 00z WRF-GFS for the same time…almost the same.
All 3 show a setup for slightly stronger wind than yesterday, assuming they have the strength and position of the developing low correct. Our RPM even has the center of the low down around 965mb with an extremely tight pressure gradient in the 100 miles around the low; 980 millibars just 50 miles out. It’s going to be a historic storm up around where it makes landfall. Lucky for us, the low is far enough away that it’s not in the “big windstorm” position. That said, once again with leaves on the trees and good mixing due to the warm temps, it shouldn’t be tough to get more damage than yesterday.
I see there are still 10,000 customers out of power in PGE’s territory, there will be more this evening! Ladies and Gentlemen, get your generators ready…
Nothing of interest going on weatherwise after tonight, just cool showers.
