A powerful coastal storm impacted the region Friday through Sunday with North to Northeast Gale to Storm force winds. This resulted in several tidal cycle of minor to moderate coastal flooding Friday morning through Sunday morning, with the most widespread moderate to locally major impacts occurring with the Saturday Night high tidal cycle.

The episode as NWS OKX wrote it up.
A powerful coastal storm impacted the region Friday through Sunday with North to Northeast Gale to Storm force winds. This resulted in several tidal cycle of minor to moderate coastal flooding Friday morning through Sunday morning, with the most widespread moderate to locally major impacts occurring with the Saturday Night high tidal cycle. In addition, prolonged high surf from energetic easterly swells during this time period resulted in widespread areas of dune erosion and localized washovers along the Atlantic Ocean beachfront.

NWS New York, NY wrote its last area forecast discussion before the first event at Mar 2, 5:19 AM EST, 1 hour 41 minutes earlier.
Area Forecast Discussion
National Weather Service New York NY
519 AM EST Fri Mar 2 2018
.SYNOPSIS...
A major coastal low will impact the area through Saturday
morning. High pressure then builds in for the second half of
the weekend with another coastal storm possible for the middle
of next week.
&&
.NEAR TERM /UNTIL 9 AM THIS MORNING/...
As of 08Z: Explosive cyclogenesis occurring centered approximately
100 miles SSE of Fire Island NY or just south of NOAA Buoy
44066 with a central pressure of 987 hPa. Left exit region of
the 150+ KT Jet over NC driving the system. Latest near-term NWP
(RAP and HRRR) indicate another 10 hPa SFC PRES drop in the
next 6 hours (14Z). Thus 970 hPA low seen in the 06Z GEM at 18Z
could verify! Heavy rainfall with KJFK at 1.23" so far. Flood
advisories in affect for most of the region. Snow now across
western Orange County as temps fall into the lower 30s. Winds
gusting up to 40 mph already along the coast of Long Island (43
mph gust at Shinnecock Inlet and 44 mph at Napeague).
Winds will slowly back this morning as the low intensifies and cold
advection occurs. Dew points temperatures in the LAMP guidance may
be a good indicator of air temperature. Wet snow mix will continue
to work its way west and will likely be approaching the NY Metro (as
temps fall into the mid 30s) by mid morning.
Rainfall continues at the quarter inch per hour rate. Will likely
added SE Connecticut into the Urban/Small stream flood advisories
shortly.
&&
.SHORT TERM /9 AM THIS MORNING THROUGH 6 PM SATURDAY/...
Some changes made with the fcst this mrng.
The first is the expansion of the high wind wrng to the entire
area minus Putnam, Orange and wrn Passaic. In addition to this,
peak gusts have been increased across ern LI and ern CT to 70
mph.
The second change was to upgrade the winter weather advy for
wrn Passaic to a wrng. Snowfall totals in general were increased
for Orange and wrn Passaic.
An approximately 975 low is progged to be roughly 50 to 100
miles w of the benchmark at 18z. The 00Z RGEM/GFS/ECMWF, 3Z SREF
and 6Z NAM make up this grouping. The further wwd trend has
increased the wind threat, but has not made the snow/rain fcst
any less complicated.
While the cooling airmass associated with the upr low evidenced
by decreasing wet bulb zero heights remains a crucial component,
the wwd trend brings warmer air aloft in as well. Because of
these two factors, snowfall totals have been lowered from
roughly the Hudson River ewd, and increased elsewhere. Over a
foot of snow is now expected for some of the higher elevations
in Orange county.
Significant changes in snow amounts for the entire area are
possible with such little room for error thermally. The time
period thru noon will be critical for getting a handle of how
the rain/snow line is progressing.
The pcpn is progged to taper off after roughly 10pm. That final
deformation zone band could produce at least a coating of snow
even on LI, as nighttime occurrence will help.
With the storm about 550 miles se of Montauk 18z Sat, the fcst
dries out quickly on but the brisk flow will continue.
&&
.LONG TERM /SATURDAY NIGHT THROUGH THURSDAY/...
The pressure gradient will begin to slacken Saturday night into
Sunday, with most areas seeing winds diminishing, however
eastern Long Island could still see gusts up to 25 kt on Sunday.
High pressure then builds down moving into the northeast for the
rest of the weekend before weakening on Tuesday.
There is potential for another coastal storm to develop next week,
with both the 12Z GFS and the Euro indicating another low
developing off the Mid-Atlantic coast Tuesday night into
Wednesday. However, there are differences in the upper level
pattern leading to a lot of uncertainty at this time. The
precipitation type looks to be a combination of rain and snow
but will depend on strength, speed and location of this system.
&&
.AVIATION /10Z FRIDAY THROUGH TUESDAY/...
Deepening low pressure south of Long Island remains through today
then tracks to the south and east tonight into Saturday.
IFR in rain and fog, with brief periods of MVFR through 12Z as
ceilings remain variable.
A rain/snow mix develops at KSWF around 12Z becoming all snow early
this afternoon. A transition to a rain/snow mix continues to the
coast this afternoon. Four to six inches of snow is possible at KSWF
with little accumulations at the remainder of the terminals.
NE winds back to northerly early this morning, and increase. Winds
remain N/NW and continue to increase into this afternoon, reaching
peak sustained and gust levels after 19Z, then diminish this
evening. LLWS remains likely later this morning into this evening.

.OUTLOOK FOR 06Z SATURDAY THROUGH TUESDAY...
.Late Friday night...VFR NNW 20-25 kt with gusts 35-50 kt.
.Saturday...VFR. Wind N 20-30 kt with gusts 30-40 kt and
diminishing.
.Sunday-Monday...VFR.
.Tuesday...VFR with rain possible late or at night.
&&
.MARINE...
Storm force winds thru tngt decrease to gale on Sat. There could
be a few gusts to hurricane force, particularly on the ern
ocean, this aftn and eve.
Gale force winds are still anticipated on the waters east of
Moriches inlet Saturday night. Overall, winds will be trending down
at this point as the coastal low pulls further offshore. SCA
criteria wind gusts will then extend into Monday, before falling
below criteria Monday night. Ocean seas will likely remaining at SCA
levels throughout the period.
&&
.HYDROLOGY...
Two to four inches of rain/liquid equivalent are forecast with
the storm. Higher amounts are possible with this event
depending on where banded precipitation sets up. A Flood Watch
remains in effect for most of the area. Flooding of smaller
streams and rivers is possible. Poor drainage and urban
flooding will continue. Coastal flooding may enhance the flood
threat.
&&
.TIDES/COASTAL FLOODING...
A powerful coastal storm will impact the region through
Saturday Night with 24-36 hrs of N-NE gale to storm force
winds. Impacts could even linger into Sunday as the powerful
storm slowly departs. Generally 1 to 1 1/2 ft of surge is needed
for minor flooding and 2 to 2 1/2 ft for moderate flooding
during the high tide cycles today and tonight.
Surge guidance has come into good agreement with moderate
coastal flood thresholds being reached along the southern bays
of Nassau County and Jamaica Bay this morning. Elsewhere
generally minor to locally moderate coastal impacts expected.
There is still quite a bit of model spread for tonight's high
tidal cycle, with competing factors of increasing energetic
easterly swells and Ekman pumping versus strong offshore winds.
A middle of the road approach continues, with a moderate
coastal flood threat for all the waters surrounding Long Island
and lower New York Harbor. Elsewhere,the strong offshore flow
should limits impacts to generally minor to locally moderate.
With Saturday into Saturday Night high tidal cycles, the most
widespread potential for moderate coastal flooding exists. this
as Ekman pumping and energetic easterly swell energy along with
weakening offshore flow should help water levels continue to
build along the coast. Localized major coastal flooding is a low
to moderate possibility for the south shore bays during
Saturday morning and night high tides. NOTE: For those with
concerns along the bays areas, water levels may linger well
after high tides.
A minor to moderate coastal flooding threat will likely continue
into Sunday morn/aft high tides.
Finally, the USGS Coastal Hazard Viewer conitnues to depict
potential for a prolonged threat for areas of dune erosion and
localized washovers Sat thru Mon.
Confidence and clarity on local coastal impact details for
Friday Night into Saturday Night should increase today, so
continue to monitor subsequent forecasts for the latest.
