Description

What

Up to three feet of inundation above ground level in vulnerable areas near the waterfront and shoreline.

Where

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

When

Until 6 PM EDT this evening. * COASTAL IMPACTS...Locally moderate flooding is expected in the most vulnerable locations near the waterfront and shoreline. Some roads and low lying property including parking lots, parks, lawns and homes/businesses with basements near the waterfront will experience shallow flooding. * SHOREFRONT AND BEACH IMPACTS...Breaking waves of 2 to 5 feet, 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.

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.
