...COASTAL FLOOD WATCH REMAINS IN EFFECT FROM FRIDAY EVENING THROUGH
LATE SATURDAY NIGHT...

The National Weather Service in New York NY has issued a Coastal
Flood Warning, which is in effect from 6 AM to 11 AM EST Friday.

* LOCATIONS...Along the Southern Bays of Long Island,
   Jamaica Bay in Queens and the Atlantic Ocean beachfront.

* TIDAL DEPARTURE...1 1/2 to 2 1/2 ft on Friday, and potentially
  2 to 3 ft above astronomical tides on Saturday.

* TIMING...Moderate Coastal Flooding expected Friday morning.
  Potential for moderate coastal flooding during the times of high
  tide Friday Night into Saturday Night.

* COASTAL FLOOD IMPACTS...There is potential for several tidal
  cycles of widespread flooding of vulnerable areas near the
  waterfront and shoreline Friday Night into Saturday Night. 2 to
  3 feet of inundation above ground level in low lying, vulnerable
  areas is possible. This 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. Vehicles parked in vulnerable areas near
  the waterfront would become flooded. Flooding would also extend
  inland from the waterfront along tidally affected rivers.

* SHORELINE IMPACTS...Breaking waves will likely result in
  significant beach erosion Saturday through Monday. Areas of
  dune erosion and localized washovers are possible.

* UNCERTAINTY...There is currently low to moderate confidence on
  the magnitude of coastal flooding Friday Night, but potential
  remains for moderate coastal flooding. Moderate confidence
  continues in potential for moderate coastal flooding during
  the times of high tide Saturday. The potential for isolated
  major coastal flooding is currently low.

PRECAUTIONARY/PREPAREDNESS ACTIONS...
