I assume you are speaking of the TABS model, which I incorrectly described as the TABB model earlier. The three TAB models are generally unreliable and are not used in the ensemble models or for forecasting.
TABS is reaching that crazy result by far over-estimating the effect of a low pressure system in the Gulf of Mexico west of Florida, while not properly estimating other factors, thus the ridiculous trip to the west.
I am not sure why they insist on cluttering the model sheet with the TAB models and other unreliable models.
A Hurricane Watch is up from Deerfield Beach north to the Brevard/Volusia County line. A Tropical Storm Watch is up for Lake Okeechobee and North of Golden Beach to Deerfield Beach. A Tropical Storm Warning is up for Deerfield Beach to Sebastian Inlet.
If it hit at that strength, there would be a virtual 100% destruction/100% kill zone along the path of the eye and about 5 miles either side of the eye for the first several miles of landfall.
