Synopsis for Keys coastal waters from Ocean Reef to Dry Tortugas
416 AM EDT Tue Jun 9 2026
.SYNOPSIS...Gentle to moderate east to southeasterly breezes will
persist across the Florida Keys waters through the first half of
the week. Shower chances will remain near normal to slightly above
normal while southeasterly winds in the lower levels of the
atmosphere continue to direct low level moisture across South
Florida. Later in the week, a surface high is primed to move from
the New Jersey coastline into the Atlantic, which will allow
breezes to slacken. The overall flow of moisture is expected to
shift west at the same time, which would let shower chances
decrease.
