Patchy fog will limit visibility Monday morning on Long Island waters, the National Weather Service said in its marine forecast.

The service's Upton office said a weak pressure gradient will keep water conditions "below small craft advisory conditions through Tuesday."

The areas of fog, which will limit visibility to 1 to 3 nautical miles, are expected to dissipate during the late morning and then redevelop Monday night through Tuesday morning.

For most of Monday, daily high temperatures across Nassau and Suffolk counties are expected to be in the low 60s with cloudy conditions.
