Coastal Flood Advisory
Issued: 9:31 AM May. 22, 2025 – National Weather Service
...COASTAL FLOOD ADVISORY REMAINS IN EFFECT FROM 2 PM THIS AFTERNOON TO 11 PM EDT THIS EVENING... * WHAT...Up to 1 1/2 half foot of inundation above ground level expected in vulnerable areas near the waterfront and shoreline. Up to 1/2 ft of inundation above ground level possible for vulnerable areas near the waterfront and shoreline of southern Nassau with the early Thursday morning high tide. * WHERE...Northeast Suffolk, Southwest Suffolk, Southeast Suffolk and Southern Nassau Counties. * WHEN...From 2 PM to 11 PM EDT Thursday. * COASTAL FLOOD IMPACTS...Minor flooding in the most vulnerable locations near the waterfront and shoreline. Expect up to 1 1/2 feet 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. * SHORELINE IMPACTS...Along the north shore of the south fork of Long Island, breaking waves of 1 to 3 ft may cause dune erosion and localized washovers, as well as enhance splashover and flooding onto shoreline roads and properties. Along the ocean front and Orient Point, breaking waves of 4 to 6 ft on an east to west sweep will result in beach erosion and beach flooding during the times of high tide. Localized dune erosion is possible. * ADDITIONAL DETAILS...Highest confidence in widespread minor coastal flooding is along the Great South bayfront of Nassau County, and along the north shore of the south fork of Long Island, Orient Point and tidally affected portions of the Peconic River. Coastal flooding is likely to be more isolated for the central and eastern Great South Bay, Moriches Bay and Shinnecock Bay communities, but tidal piling presents potential for more widespread minor coastal flooding. 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.
