NWS Marine Forecast


   ANZ200-191600-  1005 PM EST Sat Jan 18 2025    .Synopsis for Massachusetts and Rhode Island coastal waters...  A cold front approaches today bringing a period of small craft  southerly wind gusts out ahead of it. Brief sfc ridging early Sun  gives way to low pressure that will track near or just S of the  coastal waters later Sun into Sun night. This low will continue to  intensify Mon as it lifts north through the Canadian Maritimes. This  will result in an arctic airmass moving across the waters in the Mon  through Wed time frame. Areas of moderate freezing spray are also  expected over some of our waters too.    $$
