Latest Marine Discussion:

.MARINE... Sub-advisory caliber winds are expected across the waters given weaker gradients. Any hazardous conditions are likely going to be tied to convection, lightning, and any accompanying gust fronts/outflows. Additional thunderstorm chances are maintained in the afternoon/evening forecast. Special Marine Warnings will be required for any stronger convection. The coverage of stronger storms likely decreases into Wednesday. Through mid- week, expect mainly east to northeasterly winds with gusts up to around 10 knots. Daily chances for showers and thunderstorms lead to a risk for SMWs Thursday and Friday. Southwest winds on Thursday shift to westerly on Friday, remaining below SCA criteria each day. On Saturday, winds shift to northwesterly in the wake of a frontal passage. Update as of: 359 AM EDT Tue Jul 7 2026
