Synopsis for Keys coastal waters from Ocean Reef to Dry Tortugas
1031 PM EDT Sat Jun 6 2026

.SYNOPSIS...A broad high centered just off the southeast Atlantic
Coast will maintain gentle to moderate easterly breezes across the
Keys for the next couple of days. The high will push out into the
Atlantic early next week. However, the combination of a broad
trough riding westward across the northwestern Caribbean Sea and a
stalled inverted trough over the Bahamas will keep easterly breezes
mostly gentle through this period. Heading into mid week, all of
the previously mentioned troughing will slide westward into the
Yucatan. Heading into mid week there is the potential for
freshening southeasterly breezes. Lower level moisture should also
rise, pushing up shower and thunder chances.
