Screenshot from the Dark Sky app a while ago:
That streak of orange, pink, and blue is an "atmospheric river", known locally as The Pineapple Express. By noon local, we are likely to have set a new record for one day rain amounts.
Earlier, I tweeted thusly:
This may actually be relevant in western Washington today...#wawx @waEMD @NWSSeattle https://t.co/ce391F0Xr2— Drang (@DWDrang) December 20, 2019
Now, flash floods are not often a threat in western Washington (although regular normal floods are all too common) , but the Washington State Emergency Management Department not only "liked" the tweet, but rated it accurate.
So I've got that going for me. Which is nice.
