...COASTAL FLOOD WARNING IN EFFECT [for tonight's 9:44 pm high tide]

FROM 7 PM THIS EVENING TO 2 AM EST SUNDAY...

The National Weather Service in New York NY has issued a Coastal
Flood Warning, which is in effect from 7 PM this evening to 2 AM
EST Sunday. 

* LOCATIONS...Vulnerable areas along the south shore bays of
  Queens, Southern Nassau, and Southwest Suffolk counties
  including the ocean beachfront.

* TIDAL DEPARTURE...2 1/2 to 3 1/2 ft above astronomical tides
  today and tonights high tides, and 2 to 3 ft above for Sunday
  morning high tide.

* TIMING...Widespread moderate coastal flooding is expected with
  today and tonight`s high tide. Locally major coastal flooding
  possible for tonights high tide along the Great South Bay. Minor
  to locally moderate for Sunday morning high tide.

* COASTAL FLOOD IMPACTS...Inundation of  2 1/2 to 3 1/2 feet above 

  ground level  tonight, in low lying, vulnerable areas. 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 become
  flooded. Flooding will also extend inland from the waterfront
  along tidally affected waterways.

* SHORELINE IMPACTS...Elevated water levels and breaking waves of
  4 to 8 feet will likely result in significant beach erosion
  Saturday through Monday along the ocean beachfront. Areas of
  dune erosion and localized washovers are possible. In addition 1
  to 3 ft waves along the north shore of the barrier islands may
  cause splash over sea walls, and minor damage to shoreline
  structures.

* UNCERTAINTY...There is medium confidence on the magnitude of
  coastal flooding this morning due to a large spread in surge
  model guidance. Meanwhile there is medium to high confidence
  for tonight with better agreement between models.
