Detailed Forecast


Synopsis: A weakening front with improving sea conditions across across the region today. Strong southeasterly winds out of Dixon Entrance into Clarence will weaken this afternoon. Seas will also diminish across the Gulf, outer coastal waters and southern inner channels through the day. Winds and seas will then be fairly benign through midweek. A potential gale force system working into the western Gulf looks to bring increasing winds and seas late week into the weekend.
