Coastal Waters Forecast for Florida
National Weather Service Tampa Bay Ruskin FL
325 AM EDT Mon Sep 23 2024

Gulf coastal waters from Bonita Beach to the mouth of the
Suwannee River out to 60 NM.

Important notice to mariners...marine forecasts are issued at
least four times a day. Boaters on extended trips should
routinely monitor subsequent forecast issuances and updates for
the latest marine weather information.

The wave heights are forecast as significant wave height which is
the average of the highest one-third of the waves. The highest
waves may rarely be twice the significant wave height. The winds
and seas near thunderstorms may be higher than forecast.

Synopsis for the coastal waters from Bonita Beach to Suwannee River-
325 AM EDT Mon Sep 23 2024

.SYNOPSIS...
An easterly flow will prevail through mid-week, with the highest
winds in the evening as resistance to the flow along the coast
breaks down, allowing the winds to accelerate. A few thunderstorms
could also develop and move over coastal waters around the same
time. Away from thunderstorms, peak wave heights during this time do
not look to exceed 2 feet. However, winds and seas begin to build by
mid-week, becoming dangerous for boaters by Thursday as a tropical
system moves into the Gulf. These dangerous conditions will last
into the weekend, before gradually subsiding thereafter. However,
lingering moisture will keep higher chances for storms in the
forecast into next week.
