Red Tide has likely been present from time to time in the Gulf Stream but now that South Florida is in a persistent, easterly, onshore wind, some of the HAB is being carried toward the beaches.

It’s not surprising the toxins would show up on the Palm Beaches first as that area is closest to the Gulf Stream.
