Low Pressure Record?
Yesterday, as a massive storm swept over the West Coast, the barometric pressure dropped to levels usually associated with hurricanes and cyclones. Here at our weather station in Hood River, the barometer bottomed out at 28.91 inches Hg.
I haven't been able to find a barometric pressure historical database for Hood River, but yesterday's reading is the lowest at our station since we started it 10 years ago. The previous low was 28.94 on December 16, 2002.
The Columbia River Gorge is well known for its high winds, but an odd characteristic of most of these extreme winter west coast windstorms is that the Gorge (especially around Hood River) stays remarkably wind-free. The winds yesterday were calm with a peak "gust" of 7 mph. For some reason, the pressure differential from Portland to The Dalles stays pretty much flat in these storms, and therefore little wind occurs here.
Is anyone aware of any historical barometric databases for Hood River? Any observations from your own barometers from yesterday?
I had 28.94 here in White Salmon yesterday at 1731 hours
ReplyDeleteIt was probably aliens sucking out the pressure as they flew their spaceships over the gorge.
ReplyDeleteBest explanation I've heard so far! Actually, its the only explanation I've heard so far... Besides, supernatural explanations are so much more interesting than boring rational ones.
ReplyDeleteI suppose it's time I did a blog post on my UFO thoughts..
