Synopsis for Keys coastal waters from Ocean Reef to Dry Tortugas
1025 AM EST Wed Feb 25 2026
.SYNOPSIS...
An Atlantic ridge reaching westward across the Florida Peninsula
will pull further eastward and away from our area over the next
couple of days. As a result, breezes will gradually shift further
east and south of east. Winds will vary quite a bit due to an
ongoing land breeze and cold nearshore water temperatures. The
western flank of the ridge will lift northward this afternoon into
tonight and will generally help to freshen breezes as they shift
east southeasterly. Cautions may be required for the Florida
Straits tonight. Nearshore waters will likely remain a notch or
two lower due to still cool waters. Thereafter, winds will be
light to gentle northeast to easterly due to the general higher
pressure over the eastern United States and lower pressure to our
south.
