SYNOPSIS FOR THE COASTAL WATERS FROM BONITA BEACH TO SUWANNEE RIVER-
317 AM EDT Sat Sep 21 2019

.SYNOPSIS...
Interaction between high pressure extending west-southwest along the 
eastern seaboard and a tropical wave south of Cuba is producing a 
tight pressure gradient resulting in gusty east-northeast winds over 
the gulf coast waters. Buoys in the eastern gulf are already 
reporting winds around 20-25 knots and seas around 5-7 feet off 
shore. A Small Craft Advisory for the gulf coast waters will 
continue through Sunday morning with Small Craft Exercise Caution 
for Tampa Bay and Charlotte Harbor. Winds will decrease to around 
10-15 knots on Sunday and continuing through next week as high 
pressure shifts south allowing for the gradient to slacken. No other 
marine impacts are expected through the period.
