Drunken Storm: a storm that circles around and has minimal forward motion, in contrast to normal storms that move rapidly to the east or northeast.
Tomorrow, an usually powerful storm for our region will careen around in our offshore water for an extended period before making landfall. A very strong storm and unusual behavior.
Her is an infrared satellite image of the inebriated storm at 9:45 PM Wednesday: it looks kind of funny, don't you think? Not very symmetric or well formed.
So let's view the strange behavior, using the latest UW WRF model forecasts.
At 1 AM Thursday morning, the powerful storm (969 mb!) is due west of WA State. Very large pressure gradients over the ocean...which means big winds.
1 AM Friday--it is still out there! Now just SE of Vancouver Is. Staggering.
And did I mention the big waves and flooding along the Washington coast? I should have.
Take a look at the predicted significant wave heights (the average of the 1/3 highest waves) on Thursday at 7 AM. Wow...some are 12 meters high! (around 40 ft)
And there will be plenty of precipitation during the next 72 hours, with most substantial torrents over Oregon and northern CA (see 72h predicted total below), where 5-10 inches may fall in the mountains. Lots of moisture will be spun off from the drunken storm.
And there is a lot more I don't have time to talk about, such as lots of sun in the mountains, cooler temperatures, and even the potential for lowland snow. The atmosphere is not done with us yet.
