Synopsis
Light winds and relatively low seas continue through Thursday outside isolated thunderstorms, which could produce brief strong and erratic wind gusts. A cold front moves through the coastal waters today into the evening, followed by strengthening northerly to northeasterly winds and building seas through Thursday. Winds should remain around 15 knots during this period. Winds shift to more NE to E by the end of the week with speeds at or below 20 knots.
