Synopsis for the coastal waters from Bonita Beach to Suwannee River-
852 PM EDT Fri May 9 2025

.SYNOPSIS...
A predominant southeast through southwest wind flow around 10-15
knots will prevail over the eastern gulf waters through the weekend
and into early next week. Main hazard each day will be scattered
showers and thunderstorms capable of producing locally gusty winds.
A surface low and frontal boundary will develop over the central
gulf and move eastward over the weekend, which will bring a very wet
weather pattern over the eastern gulf waters with even higher
chances of showers and thunderstorms on Sunday, Monday and Tuesday.
This system pushes south and east of Florida by Tuesday evening
allowing for clearing conditions as high pressure builds into the
central and eastern gulf waters.
