Synopsis for the coastal waters from Bonita Beach to Suwannee River-
909 AM EST Sun Dec 7 2025

.SYNOPSIS...
A frontal boundary extending across northern Florida and the
northern gulf waters will meander southeastward through the day
keeping variable winds less than 15 knots and seas 2 feet or less
through Monday morning. Showers and storms increase in coverage and
intensity through the day with numerous showers and isolated storms
expected this afternoon/evening and continuing into the early
morning hours on Monday. Some of these storms may be severe and have
the potential to produce damaging winds and brief waterspouts over
the eastern gulf waters. Mariners should use caution and remain
weather aware when operating in the eastern gulf waters today.

By Monday afternoon, the front pushes southeast of Florida and high
pressure builds in from the northwest. This will clear out the rain
and storm chances, but will bring some hazardous boating conditions
with breezy north-northeast winds around 15-20 knots and seas up to
5 feet for Monday and Tuesday. Pleasant boating conditions expected
mid to late next week with winds less than 10 knots and seas less
than 2 feet.
