Coastal waters from the Lower Atchafalaya River LA to High
Island TX out 60 nautical miles including Sabine and

328 AM CDT Sun Sep 22 2024

.SYNOPSIS...
High pressure offshore will continue the trend of hot, dry and
calm conditions. Seas are below 2 feet and will stay there
through the weekend. In addition winds will be light and variable.
The pattern will start to change around midweek as a front moves
offshore, increasing winds.

In the Gulf the NHC has a 70% region for development of a
tropical cyclone. There is little consistency between individual
models or model run-to-run consistency. It will be important to
keep a close eye on the forecast for the next several days.
