Residents in coastal areas of New York are urged to exercise caution today as a Coastal Flood Warning remains in effect for several Long Island counties amid ongoing stormy weather along the East Coast.
The National Weather Service (NWS) has issued a Coastal Flood Warning for Southern Queens, Southern Nassau, and Southwest Suffolk counties, effective through late morning to early afternoon on December 19. Minor to moderate coastal flooding is expected during high tide cycles, with water levels potentially rising 1 to 2 feet above ground level in vulnerable low-lying areas.
According to the NWS New York office, the warning stems from a persistent coastal storm system bringing strong onshore winds and elevated tides. High tides this morning could inundate shore roads, parking lots, parks, and basements in homes or businesses near the waterfront. Drivers are advised to avoid flooded roadways, as even shallow water can be dangerous.
What to Expect from the Coastal Flood Warning
- Affected Areas: Primarily southern sections of Queens, Nassau, and Suffolk counties on Long Island, including communities along the South Shore and near bays.
- Timing: Peak impacts around morning and afternoon high tides on Friday, December 19.
- Impacts: Minor flooding of vulnerable roads and properties; possible isolated closures. Saltwater inundation could affect beaches and coastal infrastructure.

This event coincides with astronomically high tides associated with the new moon phase, exacerbating the risk. While not expected to reach major flood stages, the combination of wind-driven waves. And elevated water levels has prompted the upgraded warning from advisory status earlier in the week.
Nearby areas, including parts of Brooklyn, Staten Island, and northern New Jersey, are under Coastal Flood Advisories. With similar but less severe expected inundation.
Understanding Coastal Flood Warnings vs. Advisories
The NWS uses specific terminology for coastal flooding:
- Coastal Flood Advisory: Minor flooding expected, causing inconveniences like wet roads or minor property impacts.
- Coastal Flood Warning: Moderate to major flooding likely, with potential for roadway impassability, damage to structures, or need for evacuations in extreme cases.
Residents in warned areas should secure outdoor items. Move vehicles to higher ground if possible, and stay informed via local alerts.
Broader Weather Context
This coastal flooding is part of a larger nor’easter-like system affecting the Mid-Atlantic and Northeast, bringing gusty winds, heavy rain, and rough surf. Dangerous rip currents and beach erosion are also concerns along the Atlantic seaboard.
The storm follows a pattern of increased high-tide flooding events noted in recent years, influenced by sea level rise and seasonal tidal variations. NOAA’s high-tide flooding outlook for December highlighted elevated risks around the new moon on December 19.
Safety Tips During Coastal Flooding:
- Never drive through flooded roads – turn around, don’t drown.
- Avoid walking near shorelines with pounding waves.
- Protect property by elevating valuables and unplugging electronics in basements.
- Monitor updates from the NWS and local emergency management.
