.MARINE... SCA remains in effect for the northern and middle waters for NW winds gusting up to 20 kt for today. Winds subside tonight before ramping back up the second half of Saturday. Southerly channeling effects ahead of a potent cold front will likely require Small Craft Advisories across all waters through Saturday night. Behind this strong cold front, additional advisories are likely needed on Sunday with gusts of 30 kt. Given the deeper mixing this time of the year, stronger gusts to gale force are possible. Small Craft Advisories are likely on Monday as continued northwest winds flow 15-20 knots. Winds shift southerly on Tuesday as gusts fall below SCA guidelines by the early morning. Update as of: 901 AM EDT Fri Apr 17 2026
