Detailed Forecast


Synopsis: Generally favorable marine conditions continue with relatively light winds and seas expected across the local waters. Winds will remain easterly into the start of the new workweek. However, a gradual transition to a more southeasterly or perhaps even southerly direction is anticipated as the week progresses. A weak low-level disturbance may generate a few scattered showers and maybe a thunderstorm or two through the week, especially over the Atlantic waters. Areas of sea fog may be possible during the overnight and morning hours across portions of the Gulf waters. Patchy dense fog cannot be ruled out.

Gulf Stream Hazards...None.
