Coastal Flood Warning issued September 26 at 4:23PM EDT until September 27

* WHAT...For the Coastal Flood Warning, 1 1/2 to 2 ft, locally 2
1/2 ft, of inundation above ground level in vulnerable areas
near the waterfront and shoreline. For the High Surf Advisory,
large breaking waves of 6 to 10 feet in the surf zone. For the
High Rip Current Risk, dangerous rip currents.

* WHERE...Southeast Suffolk County.

* WHEN...For the Coastal Flood Warning, until 6 PM EDT Sunday.
For the High Surf Advisory, until 8 PM EDT Sunday. For the
High Rip Current Risk, through Sunday evening.

* COASTAL FLOOD IMPACTS...Widespread moderate to locally major
flooding of vulnerable areas near the waterfront and shoreline.
The threat for localized major flooding is mainly for the north
shore of the south fork, tidally affected Peconic River, and
north shore of Fire Island due to high wave action exacerbating
flooding. This will result in numerous road closures and cause
widespread flooding of low lying property including parking
lots, parks, lawns, and homes and businesses with basements near
the waterfront. Vehicles parked in vulnerable areas near the
waterfront will likely become flooded. Flooding will also extend
inland from the waterfront along tidal rivers and bays.

* SHOREFRONT AND BEACH IMPACTS...Breaking waves of 6 to 10 feet
along with elevated water levels will result in widespread
dune erosion and beach flooding. Localized overwashes are
possible where dune structures are compromised, resulting in
some flooding of roadways and vulnerable structures behind
protective dunes. Dangerous swimming and surfing conditions
and localized beach erosion. Life threatening rip currents are
likely for all people entering the surf zone. Anyone visiting
the beaches should stay out of the surf. Rip currents can
sweep even the best swimmers away from shore into deeper water.

* ADDITIONAL DETAILS...Additional rounds of minor coastal
flooding are possible for the Sunday night into early next week
high tides.
