Coastal Flood Warning
Issued: 8:18 PM Oct. 11, 2025 – National Weather Service
...COASTAL FLOOD WARNING NOW IN EFFECT FROM NOON SUNDAY TO 7 PM EDT MONDAY... * WHAT...Major coastal flooding likely, 2 1/2 to 3 ft of inundation above ground level expected in vulnerable areas near the waterfront and shoreline for the Sunday afternoon, Sunday Night and Monday afternoon high tide cycles. Locally up to 3 1/2 ft of inundation possible. This poses an elevated threat to life and property! * WHERE...Southwest Suffolk County. * WHEN...From noon Sunday to 7 PM EDT Monday. * COASTAL FLOOD IMPACTS...There is an elevated threat to life and property! Widespread moderate to MAJOR coastal flooding expected, with 2 1/2 to 3 ft of inundation above ground level in vulnerable areas near the waterfront and shoreline, particularly for the Sunday Night and Monday afternoon high tides. This will result in numerous road closures and widespread flooding of low lying property including parking lots, parks, lawns and homes/businesses near the waterfront. Flooding may extend well inland from the waterfront and shoreline along tidal inlets, rivers and bays, which could flood some roads, homes and business that typically don't experience flooding. Cars parked in vulnerable areas will likely be flooded and damaged. * SHORELINE IMPACTS...Large breaking waves of 8 to 12 ft along the oceanfront on an east to west sweep will result in significant beach erosion and flooding. Widespread dune erosion is likely with localized overwashes possible, resulting in damage to dune structures and localized flooding of roadways and vulnerable structures behind protective dunes. * ADDITIONAL DETAILS...Water may not fully recede for the most vulnerable waterfront streets and properties between successive high tides Sunday afternoon into Monday afternoon, which could limit access to these areas for much of this 24 hr period. PRECAUTIONARY/PREPAREDNESS ACTIONS... There is an elevated threat to life and property! Take the necessary actions to protect flood-prone property. If travel is required, do not drive around barricades or through water of unknown depth. && Time of high total tides are approximate to the nearest hour.
