Latest Marine Discussion:
.MARINE... Background wind fields remain below advisory threshold through early Sunday. Ahead of a cold front, southerly winds increase in earnest which will carry gusts to around 20 to 25 knots. This likely requires Small Craft Advisories from Sunday afternoon into the overnight hours. Additionally, there will be an increasing risk of strong to severe thunderstorms, many of which may need Special Marine Warnings. Sunday likely presents itself as the most hazardous day to be on the waters, particularly from the afternoon onward. Convection may continue into Monday morning before the storm threat and winds drop off through the day. Winds stay below SCA thresholds on Tuesday. Beginning Wednesday afternoon, wind gusts pick up to marginal SCA thresholds before diminishing overnight. Northwest winds shift southeast by Wednesday morning. Update as of: 449 AM EDT Sat Aug 15 2026
