1026 AM EDT Tue May 12 2026
.SYNOPSIS...Breezes are light to gentle across the Florida Keys
waters. The lack of a strong pressure gradient suggests variable
conditions are possible tonight, but a shift towards westerlies is
expected on Wednesday. Local freshening of breezes near South
Florida is possible during the middle of the week. Shower chances
will remain on the lower side while drier air masses linger over
the Keys.
