Synopsis for Keys coastal waters from Ocean Reef to Dry Tortugas
932 AM EDT Sat May 2 2026
.SYNOPSIS...Gentle to moderate breezes this morning will slacken
today into tonight as the pressure gradient flattens. A weak
disturbance in the Gulf coupled with increased moisture will
support elevated rain and thunder chances beginning tonight,
peaking Sunday night, and tapering off over the following couple
of days. A ridge building over the Gulf and the Florida Peninsula
will support a return to dry conditions with light to gentle breezes
shifting clockwise, eventually becoming east to southeasterly.
