Exodus out of Florida


There were signs of light migration over south Florida last night, while the bulk of bird movement took place to the north. Here’s the radar from sunset last night through 7:00am this morning (still trying to adjust to getting up at 5am again… sorry).

Frames are every 1/2 hour for reflectivity and velocity, and every hour for the regional composite. Click on the thumbnail to view the full-sized animation.

A stalled front across the Appalachians and Carolinas set up a wind gradient that set off a moderate to heavy migration of birds out of the Gulf coast and southeastern states. You can see the strong echoes along the Gulf Coast on the regional composite. Otherwise, the majority of movement over Florida was into and out of the northern part of the state. A small pulse can be seen arriving from Cuba late last night, and another from the eastern Caribbean by early morning, but these pale in comparison to the amount of birds leaving the state. Best bets today will be migrant traps along the northern border of Florida.
