Re: ATL: IOTA - Models
The HWRF seems to be overdoing EWRCs on this run. The first EWRC begins when this is just a newly intensified Cat 1, and the second one begins like 12-18 hours later.

I am only a meteorology enthusiast who knows a decent amount about tropical cyclones. Look to the professional mets, the NHC, or your local weather office for the best information.

18z HWRF and HMON. HMON shows rapid strengthening up until landfall with once again a high-end cat 4 now already at 54 hours. HMON shifted north by about 0.4 degrees compared to 12z so now a border landfall. HWRF is a bit faster and further south this time and already seems to have some land interaction at 48 - 51 hours which prevents further strengthening in the last hours before landfall but it still has a strong hurricane landfall near the Nicaragua/Honduras border.

Re: ATL: IOTA - Models
I've never been a big fan of hurricane models until this year.... They've surely improved in performance and they have been much more reliable than global model
Well the GFS PARA was the best in my opinion for global models
Iota seems to be be following the hurricane model’s predictions in terms of intensity

All observations are in Tecumseh, OK unless otherwise noted.
Winter posts are focused mainly for Oklahoma & Texas.
Take any of my forecasts with a grain of salt, refer to the NWS, SPC, and NHC for official information
Never say Never with weather! Because ANYTHING is possible!

The sheer size of the system is making winds lagging behind pressure drop for now. A gigantic eye will eventually emerge if HWRF were to be believed.
