...COASTAL FLOOD ADVISORY REMAINS IN EFFECT UNTIL 5 PM EST THIS

AFTERNOON...



* LOCATIONS...Vulnerable areas along the north shore of Suffolk 

  County and Peconic Bay.



* TIDAL DEPARTURE...2 to 2 1/2 ft above normal. 



* TIMING...Late this afternoon.



* COASTAL FLOOD IMPACTS...Shallow flooding is expected in the 

  most vulnerable locations near the waterfront and shoreline. 

  Expect around 1 to 2 feet of inundation above ground level in 

  low lying, vulnerable areas. Some roads and low lying property 

  including parking lots, parks, lawns and homes/businesses with 

  basements near the waterfront will experience shallow flooding.



* SHORELINE IMPACTS...Breaking waves of 1 to 2 ft along the 

  north shore of Long Island will result in some beach erosion 

  and wave splashover. Changing water levels will also move

  ice, which could cause damage to some docks. 



PRECAUTIONARY/PREPAREDNESS ACTIONS...



A Coastal Flood Advisory indicates that onshore winds and tides

will combine to generate flooding of low areas along the shore.

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