414 PM EST Wed Feb 28 2018



...COASTAL FLOOD WATCH REMAINS 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 2 to 3 forecast, 

  predictability is moderate to now high on track and intensity 

  of this storm. Confidence and clarity on local coastal impact 

  details should increase over the next 24 hrs, so please 

  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.

Time of high total tides are approximate to the nearest hour.
