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 Sunday midday high tides.

* WHERE...Northeast Suffolk County.

* WHEN...Until 6 PM EDT Sunday.

* COASTAL IMPACTS...Minor to 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 4 to 8 ft, along with elevated water levels, will result in areas of dune erosion with damage to a few waterfront structures. Splashover over seawalls and overwashes where dune structures are compromised may locally exacerbate flooding of roadways and vulnerable structures behind protective dunes.

* ADDITIONAL DETAILS...Additional rounds of minor coastal flooding are possible for the Sunday night into early next week high tides.
