Description
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.
Instructions
Take the necessary actions to protect flood-prone property. If travel is required, do not drive around barricades or through water of unknown depth.
