Alert Details

The National Weather Service in Upton, NY, has issued a Coastal Flood Warning (Alert Code: CFW). This warning indicates that widespread moderate flooding is likely in vulnerable areas near the waterfront and shoreline.

Affected Areas

The following geographic regions are included in this warning:

  • Bronx
  • Northwest Suffolk
  • Northern Queens
  • Northern Nassau

What You Should Do

Residents should take necessary actions to protect flood-prone property. If travel is required, do not drive around barricades or through water of unknown depth. Avoid parking vehicles in vulnerable areas near the waterfront, as they will likely become flooded. Residents in homes or businesses with basements near the waterfront should prepare for potential flooding.

Expected Conditions

Inundation of 1 1/2 to 2 1/2 feet above ground level is expected in low-lying, vulnerable areas. This will likely result in numerous road closures and flooding of property including parking lots, parks, and lawns. Breaking surf of 3 to 5 feet along north and northeast facing shorelines will cause beach flooding and dune erosion during high tide. Ice cover in bays and harbors may exacerbate flooding and cause damage to shoreline structures. Conditions are dependent on the timing of a windshift from northeast to north storm force winds.

Timeline

The warning is effective from midnight Sunday night, February 23, until 5:00 AM EST Monday, February 23. The alert was originally issued on February 21 at 2:44 PM EST.
