Detailed Forecast


Synopsis: A weak southeast flow will develop today as surface high pressure moves east of the region. Onshore flow and seas will gradually increase tonight and Wednesday. A few showers will be possible on Wednesday due to increasing moisture ahead of an approaching cold front. Showers along with a few thunderstorms will be possible Wednesday night. The cold front will move through the coastal waters by noon Thursday. Gale conditions will be possible across the nearshore and offshore waters due to the very strong offshore flow that will develop behind this front, with gusts to gale force likely over the bays and waterways. Large seas will also build through Friday morning. Offshore flow and seas will slowly subside by Friday afternoon through Saturday morning. An onshore flow will develop by early Saturday evening as high pressure moves east.
