More SE Winds = Flyover Weather

Hey all,

The birds are back at it again, migrating from their wintering grounds to their breeding grounds, a mad dash to be the first male on territory. It’s no coincidence that weather phenomenons and bird migration coincide. Every spring, high pressure systems dominate the forecast at many of Florida’s birding destinations. Southeasterly winds persist, helping birds with a serious tailwind that allows them to fly farther, faster and in a northwesterly direction; out and over the Gulf instead of Florida. This route is a risky one for migrants, but remember, it’s a mad dash to be the first male on territory! These neotropical migrants are choosing a route which puts them on a much longer and riskier flight, only one thing can be on their mind, get back home. Only the best survive such a trip!

Last night was a great night for migrants once again. Birds had a decent tailwind and southeasterly winds which vectored birds NW. You can see this by looking at the velocity radar loop for Key West. Looks like the Key West radar recorded a moderate movement of migrants out over the FL Straits. Miami radar shows a small movement out of the Bahamas, but nothing much in the way of bird migration. We await a change in winds to improve birding conditions on the ground for birders, for now, look for those birds that trickle in. There are always some birds that will come in to refuel and rest before they take off again.
