Coastal Flood Warning

* WHAT...1 to 2 ft, locally 2 1/2 ft, of inundation above ground level expected in vulnerable areas near the waterfront and shoreline. The highest water levels are likely with the Saturday midday and possibly Sunday midday high tides.

* WHERE...Bronx, Northwest Suffolk, Northern Queens and Northern Nassau Counties.

* WHEN...During the times of high tide until 6 PM EDT Sunday.

* COASTAL IMPACTS...Minor to locally moderate flooding is expected in the most vulnerable locations near the waterfront and shoreline. Expect 1 to 2 ft, locally 2 1/2 ft, 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.

* SHOREFRONT/BEACH IMPACTS...Breaking waves of 3 to 6 ft, along with elevated water levels, will result in areas of dune erosion with damage to a few waterfront structures possible. Splashover over seawalls and overwashes where dune structures are compromised may locally exacerbate flooding of roadways and vulnerable structures behind protective dunes.

* ADDITIONAL DETAILS...Another round of minor to moderate coastal flooding is possible for the Sunday afternoon high tide cycle.
