Invest 93L is now inland over the northern Florida peninsula and will continue northwest into the panhandle today. One of the great mysteries in my young career will be why this system was not named Subtropical Storm Rina last night. The NHC's own words to describe 93L last night as Florida received hurricane-force wind gusts were "A NON-TROPICAL GALE CENTER." That's hard enough to justify over 29C water anyway, but AMSU showed a clear warm-core structure on all of its passes of 93L, and a tight 999mb low with a buoy off Cape Canaveral showing exponential drop in pressure and increase in winds as the center came near is a signature that is only seen in tropical cyclones. In my mind there is no way to excuse the goof-up that happened last night. Hopefully someone does something about it in the post-season. Florida knows what they got hit with last night.
Hurricane Jova is moving northeastward towards Mexico with a clearing eye and will likely be a major hurricane at landfall. Our thoughts and prayers go out to the people there. Jova moving eastward illustrates how the entire monsoon circulation is shifting eastward as the MJO aggressively progresses into phase 8. One of the strongest bursts into octant 1 that we have seen in quite a while will be occurring over the next 10 days, and the Caribbean may get a shot at development within the monsoon circulation cell next week. The ECMWF shows low pressure east of the Yucatan in 7 days, and the GFS has been inconsistent with the timing, but shows development eventually as well. While the trough will be vanishing from the eastern U.S. in a week's time, it will be short-lived, as by day 10 all of the ensembles have a big trough returning to the east, indicating that any trouble brewing in the Caribbean may have an opportunity to come northeastward towards Cuba, the Bahamas, or Florida.
We shall see what happens!
