subsequent forecast issuances and updates for the latest marine

is the average of the highest one-third of the waves.
The highest waves may rarely be twice the significant wave height.

SYNOPSIS FOR THE COASTAL WATERS FROM BONITA BEACH TO SUWANNEE RIVER-
649 AM EDT Fri Sep 20 2019

.SYNOPSIS...Interaction between high pressure extending southwest
along the eastern seaboard and a tropical wave in the Caribbean south
of Hispaniola 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 knots and seas
around 5-7 feet. This has warranted the issuance of a Small Craft
Advisory for the gulf coast waters through Sunday morning. 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.
