.SYNOPSIS FOR PASCAGOULA TO ATCHAFALAYA RIVER OUT 60 NM...

The main marine concern during the next few days of the forecast
period will be the increasing threat for thunderstorms that could
produce locally higher winds and seas. Stable airmass along the
coast today will probably limit convection but not going to be the
case this weekend. Gusty outflow winds upwards of gale force are the
main threat. This pattern continues into early next week as a
backdoor cold front gradually pushes into the coastal waters. The
current wind forecast would indicate generally offshore flow by late
Sunday afternoon for most or all of the waters as a backdoor cold
front pushes in from the northeast. If the front makes it well into
the Gulf early next week, that may justify Small Craft Exercise
Caution headlines by Monday or Tuesday.
