Unusually strong wind is blasting the west end of the Columbia River Gorge this morning.
With approaching low pressure and strong high pressure to the east, the pressure gradient has jumped to the highest we’ve seen it in a least 3 years. Around 13 millibars from The Dalles to Portland. I don’t remember the last time I’ve seen it that high. I’ve never seen it above 14 millibars. That equates to a damaging wind. Portland pressure is the bottom line and The Dalles is up top.
Peak gust at Corbett school was 77 mph this morning, also the highest in several years.
The Vista House wind sensor is a bit beat up this winter, I’ve noticed speeds have been a bit low during several events. There has been a gust to 83 mph there. Note these speeds are occurring with temperatures in the upper teens! Anyone want to go hang out on those Vista House steps and get an accurate reading??? I didn’t think so.
Peak gusts have been in the 40-50 mph range in the far eastern suburbs of Troutdale and Gresham.
The strong (damaging in spots) wind will continue through Sunday afternoon, then go mainly calm Monday and most of Tuesday.
