MARINE

Dual hazards across much of the waters expected through early Saturday with gales and freezing spray. The gale warning in effect for most waters ends at 6AM Saturday. NY Harbor will be a little less with winds, SCA in effect there until 6AM Saturday. The freezing spray with moderate accumulations forecast is where we have the freezing spray advisory issued with 0.3 to 0.8 inch accumulation of ice expected. The freezing spray advisory is in effect until 2PM Saturday for the ocean waters and the eastern half of Long Island Sound. The western half of Long Island Sound and NY Harbor have their freezing spray advisory until 12PM Saturday.

For Saturday, winds will be within SCA range and the freezing spray decreases heading into the afternoon, with eventually just light accumulations expected for parts of the waters for the afternoon.

A Gale Watch is in effect for the ocean waters and eastern Long Island Sound for Sunday Afternoon through Sunday night. There is potential for the other waters to be added to the Watch but confidence was not there at this point.

For early into mid part of next week, SCA conditions are likely across much if not all of the waters much of the time. For a part of this time, another round of gales will be possible Monday night into early Tuesday, mainly on the ocean.
