NWS / NOAA weather: Coastal Flood Warning issued September 27 at 5:36AM EDT until September 27 at 6:00PM EDT by NWS Upton NY
* WHAT...For the Coastal Flood Warning, 2 to 3 feet of inundation
above ground level in vulnerable areas near the waterfront and
shoreline. For the High Surf Advisory, large breaking waves of 7
to 9 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 this
evening. For the High Surf Advisory, until 8 PM EDT this
evening. For the High Rip Current Risk, through this evening.
* COASTAL FLOOD IMPACTS...Locally moderate flooding of vulnerable
areas near the waterfront and shoreline. The threat for moderate
flooding is mainly for the north shore of the south fork, the
tidally affected Peconic River, and the north shore of Fire
Island. 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 7 to 9 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.
