.DISCUSSION...

.KEY MESSAGE 1...
Low center was S of Long Island and E of the NJ coast as of 08Z
and should continue moving westward toward NJ today while
weakening, then stall near the NJ coast tonight, and drift
slowly E on Mon, passing S of Long Island. With the parent upper
low passing over the area expect bands of moderate to locally
heavy rain and embedded tstms to still be possible.

Not seeing winds 58+ mph anywhere in the CWA though they might
still be possible in immediate coastal areas with N-NE exposure.
Given that limited impact replaced the high wind warning across
Long Island and SE CT with a wind advisory. Advisory continues
elsewhere through this morning for potential impacts from wind
gusts 40-45 mph (just below official criteria) with trees still
leafed out and wet ground.

.KEY MESSAGE 2...
Greatest potential for bands of moderate to heavy showers will
be this afternoon and evening, with additional rainfall of 1-2
inches (locally higher across CT/Long Island) still possible.
Latest HREF prob of an inch of rain in 3 hours as high as 50-60%
across Long Island and the NYC metro area late today into this
evening, with a slight (20%) chance of 2 inches in 3 hours
across central Suffolk County late today. Still opted not to
issue a flood watch, as flooding unlikely to be considerable
and more likely in the minor nuisance category.

.KEY MESSAGE 3...
The current forecast is based on a blend of the previous
forecast the the 00Z NYHOPS 50th percentile, ETSS/PETSS 50th
percentile, and STOFS guidance. Surge models have over-performed
so did not consider the higher percentiles of probabilistic
guidance despite winds veering more NE this morning.

Coastal flood warnings will be allowed to continue for one more
tide cycle as locally major flooding may still be possible
along the back bays of S Nassau and SW Suffolk counties, with
moderate flooding also expected in spots along Peconic Bays, the
western Sound, and lower NY Harbor and Jamaica Bay, minor to
locally moderate flooding in tidally impacted areas of NE NJ,
and minor flooding along the Hudson River in the lower Hudson
Valley.

As winds diminish the coastal flood threat will lessen, with
widespread minor flooding expected during the high tide cycles
tonight and Mon morning. Some spotty minor flooding may last
into Tue and Wed with the morning high tide cycles on those
days.

.KEY MESSAGE 4...
High risk of rip currents and high surf today along ocean
shorelines, with surf heights up to 8-11 feet possible.
Additional beach erosion likely with the high tide cycle this
morning.

This will be the last issuance of routine surf zone products and
high surf advisories for the 2026 season.

.MARINE...

Island Inlet out 20 nm as winds at 44065 have been quite a bit
short. Converting any storm warnings on the non ocean waters to
gale warnings as well and running through 6 PM today for
simplicity`s sake even though gusts may come down below gale
force by early afternoon.

then hazardous ocean seas may linger E of Fire Island Inlet from
