WHAT HAS CHANGED

Added small craft advisories to all waters Sunday through Sunday night. See marine section for more details. Otherwise, no other significant changes made.

KEY MESSAGES

1) Low pressure with remnants of Isaias approaches Sunday and moves south of Long Island early Monday with overall minor impacts to the area.

2) For coastlines, possible minor coastal flooding early in the week with possible high surf for ocean beaches, especially for Long Island ocean beaches.

3) Chance of showers and possible thunderstorms Tuesday night into early Wednesday with a quick moving system.

KEY MESSAGE 3

Less amplified and longer wavelength trough in mid levels approaches Tuesday and moves across early Wednesday. At the surface, low pressure approaches from the north and west but the center of this low remains north of the region through early Wednesday. This will bring a cold front across early Wednesday.

There will be a brief chance of showers along with a possible thunderstorm with some forecast elevated instability, mainly Tuesday night. Not expecting much rainfall with this considering the lack of atmospheric moisture within the system.

OUTLOOK FOR 00Z MONDAY THROUGH THURSDAY

Sunday night: Rain with IFR cond. Local and/or brief LIFR cond possible. Slight chance of thunder after 00Z Monday. NE 10-15G20 kt with winds diminishing through the night.

MARINE

Winds and seas remain below SCA thresholds through tonight with high pressure in control. Then, approaching low and increase in pressure gradient between low to southwest and high to the northeast will make for increasing easterly winds. Winds forecast to increase Sunday, with gusts reaching SCA levels first for ocean and then for non-ocean zones in the afternoon. The SCA wind gusts last through much of Sunday night for all marine zones. Ocean seas build to near 5 to 7 ft Sunday afternoon and are forecast to be mainly 7 to 10 ft Sunday night.

Ocean seas start to lower Monday but will likely remain in SCA range into Monday night. Otherwise, winds will be lowering Monday with SCA wind gusts mainly just for the ocean. Monday night winds are below SCA for all waters.

Another possible SCA event late Tuesday night into Wednesday for parts of the ocean with otherwise mainly sub-SCA for rest of marine forecast period for the marine forecast region.

Outer ocean 20-60 nm out has potential for gales Sunday into Sunday night but only mentioned in HWO as frequency of gales only expected to be occasional. Not enough confidence for a gale watch.
