124 PM EDT Thu May 22 2025
...COASTAL FLOOD ADVISORY REMAINS IN EFFECT UNTIL 11 PM EDT THIS
EVENING...
* WHAT...Up to 1 1/2 half foot of inundation above ground level
expected in vulnerable areas near the waterfront and
shoreline. Up to 1/2 ft of inundation above ground level
possible for vulnerable areas near the waterfront and
shoreline of southern Nassau with the early Thursday morning
high tide.
* WHERE...Northeast Suffolk, Southwest Suffolk, Southeast
Suffolk and Southern Nassau Counties.
* WHEN...From 2 PM to 11 PM EDT Thursday.
* COASTAL FLOOD IMPACTS...Minor flooding in the most vulnerable
locations near the waterfront and shoreline. Expect up to 1
1/2 feet of inundation above ground level in low lying,
vulnerable areas. Some roads and low lying property including
parking lots, parks, lawns and homes/businesses with basements
near the waterfront will experience shallow flooding.
* SHORELINE IMPACTS...Along the north shore of the south fork of
Long Island, breaking waves of 1 to 3 ft may cause dune
erosion and localized washovers, as well as enhance splashover
and flooding onto shoreline roads and properties. Along the
ocean front and Orient Point, breaking waves of 4 to 6 ft on
an east to west sweep will result in beach erosion and beach
flooding during the times of high tide. Localized dune erosion
is possible.
* ADDITIONAL DETAILS...Highest confidence in widespread minor
coastal flooding is along the Great South bayfront of Nassau
County, and along the north shore of the south fork of Long
Island, Orient Point and tidally affected portions of the
Peconic River. Coastal flooding is likely to be more isolated
for the central and eastern Great South Bay, Moriches Bay and
Shinnecock Bay communities, but tidal piling presents
potential for more widespread minor coastal flooding.
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.
&&
Time of high total tides are approximate to the nearest hour.
