501 PM EDT Sun Apr 12 2020

...COASTAL FLOOD ADVISORY IN EFFECT FROM NOON TO 6 PM EDT
MONDAY...

* WHAT...Minor to locally moderate coastal flooding and shoreline
  impacts during Monday afternoon high tide.

* WHERE...Kings (Brooklyn), Northeastern Suffolk, Southwestern 
  Suffolk, Southeastern Suffolk, Southern Queens and Southern 
  Nassau Counties.

* WHEN...From noon to 6 PM EDT Monday.

* COASTAL FLOOD IMPACTS...Minor to locally moderate 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. Localized areas of 
  2 to 2 1/2 ft of inundation are possible. Several roads and low 
  lying property including parking lots, parks, lawns and 
  homes/businesses with basements near the waterfront will 
  experience shallow flooding. Vehicles parked in the most 
  vulnerable areas near the waterfront may become flooded.

* SHORELINE IMPACTS...Along the Atlantic ocean beach front of 
  Long Island, large breaking waves of 12 to 16 ft will result in 
  significant beach erosion. Areas of dune erosion and localized 
  overwashes are possible, which would result in some flooding of 
  roadways and vulnerable structures behind protective dunes. 
  Along the Brooklyn beachfront and Orient Point, breaking waves 
  of 4 to 7 ft will result in beach erosion with minor dune 
  erosion, localized damage to dune structures and wave 
  splashovers possible.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

If travel is required, allow extra time as some roads may be
closed. Do not drive around barricades or through water of
unknown depth. Take the necessary actions to protect flood-prone
property.

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