Amazingly both Ft Lauderdale and Miami Intl Airports are open and have commercial passenger flights operating. Same with Orlando.

Ian appears to have been moving steadily N instead of NNE recently. If so, was this expected?

Just like Jon Snow..."I know nothing" except what I know, and most of what I know is gathered by the fine people of the NHC

TEAL72 just made a U-turn to the west? That's an odd maneuver if they're not calling it an early night. Shoot, looks like they turned around back to Mississippi.
