Latest (within the last hour or so) infrared images of what is left of Bonnie depict a system on life support. As some things on life support do occassionally do, however, it's made a bit of a comeback as it made landfall just north of Key Largo. The latest image on the Miami radar indicates that landfall occurred at around 10:00am ET, roughly five minutes ago. Some very impressive convection formed over the apparent LLC right as the storm crossed the barrier island just offshore of the mainland. I just refreshed the radar, which loaded the 10:02am ET images, and that one shows Bonnie about to cross over the mainland coastline. On the current heading, that would put whatever is left (if anything) into the Gulf around Everglades City in a few hours.
