.SYNOPSIS FOR PASCAGOULA TO ATCHAFALAYA RIVER OUT 60 NM...
Tropical Storm Bertha will meander over the northeast gulf for the
next day or so. It is forecast to move westward along or off the
north central gulf coast. As the system moves over our local waters,
expect winds and seas to increase with tropical storm conditions
possible for most if not all the local waters. The system will move
west of the region later Thursday and conditions should improve
going into the upcoming weekend.
