Coastal Flood Warning Issued for Northeast and Southeast Suffolk Counties Through Monday Morning

Alert Details

The National Weather Service (NWS) office in Upton, NY, has issued a Coastal Flood Warning for vulnerable areas near the waterfront and shoreline. This alert indicates that widespread moderate flooding is likely during the specified time window.

Affected Areas

The warning specifically covers Northeast Suffolk and Southeast Suffolk Counties. Impacted locations include areas along Gardiners Bay, particularly Orient Point and the north shore of the south fork. Flooding is expected to extend inland from the waterfront along tidal rivers and bays.

What You Should Do

Residents are urged to take necessary actions to protect flood-prone property. If travel is required, do not drive around barricades or through water of unknown depth. Vehicles parked in vulnerable areas near the waterfront should be moved, as they will likely become flooded.

Expected Conditions

• Inundation: 1.5 to 2.5 feet of water above ground level is likely in low-lying areas.
• Shoreline Impacts: Breaking surf of 5 to 10 feet is expected along Gardiners Bay, which will cause beach flooding and dune erosion during high tide.
• Infrastructure: Numerous road closures are anticipated. Flooding may affect parking lots, parks, lawns, and homes or businesses with basements.
• Additional Hazards: Ice cover in bays and harbors could exacerbate flooding and cause damage to north to northeast-facing shoreline structures. Splashover flooding may occur behind protective dunes and seawalls.

Timeline

The Coastal Flood Warning is effective from 10:00 PM Sunday to 6:00 AM EST Monday. The water level forecast is highly dependent on the timing of a wind shift from northeast to north storm-force winds. Additional minor coastal flooding may be possible during the Monday afternoon high tide.
