Synopsis for the coastal waters from Bonita Beach to Suwannee River-
239 PM EDT Fri Jul 4 2025

.SYNOPSIS...

A stalled remnant frontal boundary and deep tropical moisture will
continue to support widely scattered to numerous shower and
thunderstorm development through the remainder of the holiday week
and into the weekend. The highest rain chances should generally
occur in the overnight and morning hours each day as southwest
flow should keep most of the precipitation activity over land
during the afternoon and evening hours but occasional storms will
be possible at any time and this may result in locally high seas
and winds in the vicinity of any of this activity. Winds outside
of any thunderstorm activity will generally be out of the
southwest at 5-10 kts throughout the weekend and slightly drier
air then begins to move into the area by next week with rain
chances decreasing slightly, though daily showers and storms will
remain possible each day and mostly favored once again in the
overnight and morning hours as onshore flow continues.
