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

Early in the forecast period, winds will begin today primarily
offshore/out of the northeast to transitioning easterly as high
pressure builds south into the NE US. What this will do over time
through the rest of the week is increase the surface pressure
gradient promoting an increase in easterly winds across the northern
and central Gulf. Given the prolonged easterly fetch setting up and
guidance in good agreement in winds reaching 15-20kts Thursday,
becoming more 20-25kts east of the Delta, waves/seas will respond
reaching 6-7ft over 20-60nm zones E and S of the delta, to reaching
9 to 10 feet going into Friday. With a high confidence forecast and
synoptic pattern setting up, went ahead with Small Craft Advisory
headlines for waters along and east of the MS delta and south of the
Sound. This will likely be expanded west with time, and extended in
duration as well. Conditions are expected to improve late into the
weekend and into early next week as winds steadily dissipate and
wave/seas back down. KLG
