Coastal Flood Warning
Issued: 3:35 PM Oct. 13, 2025 – National Weather Service
...COASTAL FLOOD WARNING REMAINS IN EFFECT UNTIL 7 PM EDT THIS EVENING... * WHAT...Moderate to LOCALLY 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 tonight and Monday afternoon high tide cycles. The probability for 3 1/2 ft of inundation is low and localized. This event poses an elevated threat to property, and potentially to life. * WHERE...Southwest Suffolk and Southern Nassau Counties. * WHEN...Until 7 PM EDT this evening. * COASTAL FLOOD IMPACTS...This event poses an elevated threat to property, and potentially to life. Widespread moderate to LOCALLY 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 tonight 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...This forecast has been weighted towards a reasonable worst case scenario to account for differences in model depiction of low pressure track and intensity, and provide a safety margin for planning. Water levels would fall on lower end or short of current forecast range if winds remain more from the north versus the northeast. PRECAUTIONARY/PREPAREDNESS ACTIONS... 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.
