Edit: The rogue "Hurricane On Demand" seems to have been removed from the projections for the 20th. This is checking at 15 hours from the original comment, below --

Here's a fun exercise...
Go to Ventusky.com and get Florida and the GoM set on the map. Choose "Wind speed" to display hurricane action. Along the bottom go to the date section and choose Wednesday, November 20th. Set the time around 4:00am or so then press the "Play" button.
Sometime between 7:00am and 10:00am - with no supporting wind patterns in that area - a powerful hurricane just pops on the scene. You can press "Pause " then "Previous" and go back in time a few times if you want to replay that. Almost looks like "Hurricane On Demand". Maybe that's "normal", but I've been watching Ventusky for over a year and haven't seen that before. There's always been some rotating air that strengthens, forms and picks up speed. Going from a southern wind with no rotation whatsoever in that area to a powerful hurricane within three hours seems strange, but then these are strange times we live in.
