Strong winds and coastal flooding for my area

Northeast Suffolk-Southwest Suffolk-Southeast Suffolk-
Southern Queens-Southern Nassau-
341 PM EST Tue Dec 20 2022

...COASTAL FLOOD WATCH IN EFFECT FROM LATE THURSDAY NIGHT THROUGH
LATE FRIDAY NIGHT...

* WHAT...One to three feet of inundation above ground level
possible in vulnerable areas near the waterfront and shoreline.

* WHERE...Northeast Suffolk, Southwest Suffolk, Southeast
Suffolk, Southern Queens and Southern Nassau Counties.

* WHEN...From late Thursday night through late Friday night.

* COASTAL FLOOD IMPACTS...There is potential for widespread
moderate to major flooding of vulnerable areas near the
waterfront and shoreline. There is potential for 2 to 3 feet of
inundation above ground level in low lying, vulnerable areas,
which would result in numerous road closures and cause
widespread flooding of low lying property including parking
lots, parks, lawns and homes/businesses with basements near the
waterfront. A few buildings and homes near the waterfront could
experience flooding. Vehicles parked in vulnerable areas near
the waterfront will likely become flooded. Flooding could also
extend inland from the waterfront along tidal rivers and bays.

* SHORELINE IMPACTS...Along the ocean front, 10 to 15 ft breakers
(highest across eastern Long Island) will likely result in
widespread beach flooding and erosion during the times of high
tide. Areas of dune base erosion and localized overwashes are
likely as well. Along the south shore of the north fork of Long
Island, particularly Orient Point, 3 to 6 ft breaking waves will
result in beach erosion and erosion of dune structures. Wave
splashover of dune structures and bulkheads is possible in
spots, which would cause flooding of roadways and vulnerable
structures behind protective structures.

* ADDITIONAL DETAILS...How widespread the major flooding will be
on Friday morning will depend on the direction and strength of
winds through the time of high tide. This will be refined over
the next 48 hours. There is also potential for isolated minor
flooding during the Thursday Night high tide. There is potential
for residual minor to moderate coastal flooding along eastern
portions of the Great South Bay with the Friday Night high tide.


PRECAUTIONARY/PREPAREDNESS ACTIONS...

If travel is required, allow extra time as some roads may be
closed. Do not drive around barricades or through water of
unknown depth. Take the necessary actions to protect flood-prone
property.
