418 AM EST Wed Jan 29 2025
Florida Bay, Hawk Channel and Straits of Florida from Ocean Reef
to south of Dry Tortugas, and the extreme southeastern Gulf of
Mexico, including The Florida Keys National Marine Sanctuary
Seas are given as significant wave height, which is the average
height of the highest 1/3 of the waves. Individual waves may be
more than twice the significant wave height.
Wave Detail will include details about the period and direction
of origin for the highest energy waves. Long-period swells coming
from a different direction than the wind would be included in the
Wave Detail.

.SYNOPSIS...
High pressure will continue to track eastward through our area
today, allowing for light to gentle northeast breezes to
continue. As this high tracks further eastward over the Atlantic
through the second half of the week, breezes will veer east to
southeasterly and slowly strengthen by Thursday night. An
approaching pre- frontal trough on Saturday will lead to a col
across the region with light and variable breezes possible.
