Looks likely this will be upgraded to a cat 2 in a couple hours … should have hedged properly…

Isaac designated a hurricane at the 5am advisory... forecast to reach 75kt.

I don't think they ever saw the same SAR pass I did last night as I don't see it mentioned in the discussions (focused on Helene?).

bought Ṁ65 Strong tropical stor... YES

Not too confident when EPS/12Z predicts >50% of its members having it (at least momentarily) reaching 978 MSLP

(VMax wise these global ensembles seem less helpful ...)
