Synopsis for Keys coastal waters from Ocean Reef to Dry Tortugas
1020 PM EDT Tue Oct 7 2025
.SYNOPSIS...A combination of a stationary frontal boundary and a
weak area of low pressure still situated near the Bahamas will
make for a messy weather pattern through the next several days.
This will maintain above normal rain chances through the entire
forecast period. The lax gradient will help to keep winds near
gentle to moderate, but direction will fluctuate between the
northeast and southeast at times. At this time, the strongest
breezes look to stay confined to the northern portions of our deep
Gulf waters, but we will continue to monitor model forecast
trends.
