UPDATE

Update for the 06Z TAF issuance as well as the long term discussion.

MARINE

Outer waters: Hazardous marine conditions peaked midday Wednesday, driven by a broad band low lifting through the gulf bringing southeast winds of 30-35kts, widespread Small Craft conditions, and steep, heavy ocean swells of 8-14ft. A slight chance of thunderstorms remains for the northeast coast and far southern panhandle through Thursday evening. Seas will continue to gradually diminish Wednesday night and through the day Thursday dropping to 7 ft or less by Thursday night as the low turns southward and continues to weaken. A brief break in hazardous conditions later Thursday will come to an end on Friday as a new frontal system lifts into the gulf.

Inner channels: Winds across the inner channels continue to be largely 15 kt or less Wednesday afternoon. The east/west orientation of the pressure gradient continues to support channeling of the winds in associated channels, though not as strong due to the low continuing to weaken and meander more offshore. Overnight and into Thursday the pressure gradient is expected to continue to slacken across the inner channels, leading to an overall reduction in winds speeds. As the low continues to slide southward, a weak northerly wind shift is expected. Thursday, and especially Friday, could see some light localized sea breeze effects with clearer skies expected. There is increasing confidence that these clearer skies will result in widespread fog development for Friday morning; less confidence for any patchy fog Thursday morning.
