...COASTAL FLOOD WATCH IN EFFECT FROM FRIDAY MORNING THROUGH LATE

SATURDAY NIGHT...



The National Weather Service in New York NY has issued a Coastal

Flood Watch, which is in effect from Friday morning through late

Saturday night.



* LOCATIONS...Along the Southern and Eastern 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...Potential for moderate coastal flooding during the

  times of high tide Friday and Saturday.



* COASTAL FLOOD IMPACTS...There is potential for several tidal 

  cycles of widespread flooding of vulnerable areas near the 

  waterfront and shoreline. 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 Sunday. Areas of dune

  erosion and localized washovers are possible.



* UNCERTAINTY...Since this is still a Day 3 to 4 forecast,

  predictability is moderate on track and intensity of this storm.

  It is therefore too early to provide point water level

  forecasts. Confidence and clarity on local coastal impact

  details should increase over the next 24 to 36 hrs, so continue

  to monitor subsequent forecasts for the latest.





PRECAUTIONARY/PREPAREDNESS ACTIONS...



A Coastal Flood Watch means that conditions favorable for

flooding are expected to develop. Coastal residents should be

alert for later statements or warnings...and take action to

protect property.
