NWS is getting increasingly bullish on the rainy mess in the southwest Gulf of Mexico. Which may well become Isaias here in a couple days.
This weather professional and blogger has an interesting analysis. It’s a long article, but no fluff or sensation anywhere.
What’s eyepopping to me is the map of GoM surface warmth partway down the article. Substantially the entre GoM & Florida Strait is at record warm temps. Net of a small hole of normal temps near the center of the Gulf.
Probably more of a prodigious rainmaker than wind threat, but never say never.
Minor aside: If it does become a named TS or better, I am anticipating all sorts of fun as various American newscasters try to pronounce that name per the NWS’s long-published guidance.
Semi-related aside:
I remembered that we had another storm Isiaias and corresponding thread awhile ago. Yep, 6 years ago. Since there are six annual hurricane name lists, it makes sense they’d repeat every 6 years.
