NHC @ 11pm

“Little change in strength is expected during the next 12 to 24 hours as it will likely take some time for the system to consolidate and develop a well organized circulation. Once the system is able to
close off and contract, steady strengthening is forecast as the cyclone will be over warm waters and within a region of high moisture and upper-level diffluence. However, some of the models
show an increase in shear and slightly drier air affecting the system around the time it reaches the coast. The NHC intensity forecast is raised from the previous one and lies roughly near the
middle of the guidance envelope.

The highest winds are expected to remain on the west side of the system during the next day or so, but these winds should shift to the eastern side of the circulation before the cyclone reaches the Gulf Coast.”

NHC said this at 4am:

"official track forecast has again been nudged eastward in the 48-72
hour period, but not quite as far east as the ECMWF and corrected
consensus model predictions. It should be noted that confidence in
the track forecast is lower than normal since the system lacks a
well-defined center."

I'm really curious to see what the new recon finds in a bit. Deep convection continues and increased banding is quite obvious in satellite imagery.

The ICON model which has been perhaps the most consistent with the evolution of this system has ticked eastward and puts SE Louisiana under the gun for a fairly significant hurricane.

i think we've been really lucky in that a lot of hurricane landfalls the last few years have hit the part of louisiana where crocodiles outnumber humans 20-1

It will be interesting to see how far east the soon-to-be-issued hurricane warnings extend. I expect hurricane warnings to be as far east as Grand Isle and tropical storm warnings to the mouth of the Mississippi including Lake Ponchatrain.

Edit: Yes, I wrote this before seeing the 11 AM lol.

Alligators, but I get your point. This part of the Louisiana coast is a good spot to absorb landfall.
