The 18Z model runs are in,

18Z GFS rips some energy off the larger system and spews it off to the north, with a lot of rain on the eastern side, going over Florida, the strongest part of the energy winds up near Panama City Beach on Thursday evening. With the center detaching and remaining a bit over the Gulf of Mexico. The Panhandle and Northern Florida get the majority of the rain. The disorganized center eventually makes it over the Panhandle late on Wednesday.

The GFS Para takes the system and gets it going in the Eastern Gulf with rain across all of Florida and forms a tight center which becomes a hurricane, landfalling near Panama City Beach on Tuesday evening. Then races through Georgia and South Carolina. Another low develops in the Bay of Campeche and winds up just south of TX/Mexico border on Thursday/Friday.

The 12Z Euro shifts the system west, with a possible Depression/TS just south of the TX/Mexico border on Thursday. This is a slight shift north from earlier Euro runs.

Although the Euro is the more likely scenario, we can't discount the idea that a system shoots off and forms like the GFS models suggest.
