Synopsis for the coastal waters from Bonita Beach to Suwannee River-
303 AM EDT Sun Oct 5 2025

.SYNOPSIS...

While winds are beginning to lay down across southern waters,
showers and thunderstorms continue to persist mainly in offshore
waters as a weak boundary lifts northward. For central waters
including Tampa Bay and northern waters, gusty winds will continue
to create dangerous conditions for small craft over the next
several days. Additionally, all waters will likely see showers
and thunderstorms again late this evening and overnight as storms
forming over land continue to move west into the Gulf. Winds will
also increase as these storms approach. Little change is expected
through mid-week. Thus a similar setup is expected each day.
