Marine conditions are expected to remain manageable for most vessels, with seas staying between 2 to 3 feet. However, increasing southwest winds on Thursday, with gusts up to 20 knots, may create choppier conditions, particularly near the shore. By Friday night, northwest winds could reach up to 20 knots with gusts up to 25 knots, posing challenges for smaller boats. Mariners should be cautious of shifting wind directions and increasing gusts as the cold front moves through.
