Strongest Wind in 6 Months Today

September 11, 2014

4:45pm Thursday…

The peak gust at PDX was 44 mph today, easily the strongest gust we’ve seen since back on March 6th.  That day we saw a 47 mph gust.  As a result, most of our neighborhood trees saw a little bit of “natural pruning”.  Lots of debris floating around yards and roadways.  MarkWind_PeakGustPDX

Luckily wind gusts didn’t get much stronger than that and power outages remained at less than 10,000 customers through the strongest wind this morning and midday.  As of 4pm it looks like still around 2,000 PGE customers are still out even though the strongest wind has passed.  Notice how widespread the easterly wind was in the metro area today, even Aurora had a 39 mph gusts…very unusual.

Plenty of small fires have popped up, and we’re lucky that most have them have been put out promptly, although at this hour one is threatening homes west of White Salmon in the Gorge.

Expect the wind to diminish to just “normal breezy” east wind tonight through Monday as a thermal trough sits overhead.  That means temperatures will warm up but no more strong gusts away from the west end of the Gorge.

Still, with very dry air overhead and hot afternoons, the NWS has extended the Red Flag Warning all the way through Sunday.
