Active AlertsGreat Neck, NY

What: 1 1/2 to 2 1/2 ft of inundation above ground level likely in vulnerable areas near the waterfront and shoreline.
Where: Bronx, Northwest Suffolk, Northern Queens and Northern Nassau Counties.
When: From midnight tonight to 5 AM EST Monday.
Coastal Flood Impacts: Widespread moderate flooding of vulnerable areas near the waterfront and shoreline likely. 1 1/2 to 2 1/2 ft of inundation above ground level possible in low lying, vulnerable areas. This would result in numerous road closures and cause widespread flooding of low lying property including parking lots, parks, lawns and homes/businesses with basements near the waterfront. Vehicles parked in vulnerable areas near the waterfront will likely become flooded. Flooding will also extend inland from the waterfront along tidal rivers and bays. Ice cover in the bays and harbors could exacerbate flooding and cause damage to northeast to east facing shoreline structure.
Shoreline Impacts: Breaking surf of 3 to 5 ft along north and northeast facing shorelines will cause beach flooding and dune erosion during the time of high tide. This may also exacerbate splashover flooding of shorelines roads and properties behind protective dunes, structures and seawalls. Minor damage to shoreline structures possible.
Additional Details: This water level forecast has been leaned towards a high end scenario, providing a margin of safety. It is highly dependent on timing of windshift from northeast to north storm force winds with respect to the time of high tide. If shift to northerly winds occurs earlier than time of high tide, water levels will fall to the low end or even below the forecast range. Ice cover in the bays and harbors could exacerbate flooding and cause damage to north to northeast facing shoreline structures.

Take the necessary actions to protect flood-prone property. If travel is required, do not drive around barricades or through water of unknown depth.
