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

High pressure remains in control of the forecast through the first
half of the week, helping to keep winds light. Winds may become
slightly elevated in the second half of the week as they turn
southerly, though currently still looking to remain below exercise
caution criteria. Convection will remain very isolated in nature
Tuesday and most of Wednesday before we see tropical moisture
return to the region, increasing our chances of rain and
thunderstorms.
