Coastal Flood Warning

* WHAT...For the Coastal Flood Warning, 2 to 2 1/2 feet of inundation above ground level in vulnerable areas near the waterfront and shoreline. For the High Surf Advisory, large breaking waves of 6 to 8 feet in the surf zone. For the High Rip Current Risk, dangerous rip currents.

* WHERE...Southwest Suffolk and Southern Nassau Counties.

* WHEN...For the Coastal Flood Warning, until 6 PM EDT this evening. For the High Surf Advisory, until 8 PM EDT this evening. For the High Rip Current Risk, through this evening.

* COASTAL FLOOD IMPACTS...Widespread moderate to locally major flooding of vulnerable areas near the waterfront and shoreline. Flooding could again extend inland into coastal areas that typically don't experience coastal flooding. Coastal flooding will be exacerbated along north facing shorelines from wave action, particularly for the barrier island from Atlantic Beach, Long Beach to Jones Beach. This will result in numerous road closures and cause widespread flooding of low lying property including parking lots, parks, lawns, and homes and businesses with basements near the waterfront. Vehicles parked in vulnerable areas near the waterfront will likely become flooded.

* SHOREFRONT AND BEACH IMPACTS...Breaking waves of 6 to 8 feet along with elevated water levels will result in widespread dune erosion and beach flooding. Localized overwashes are possible where dune structures are compromised, resulting in some flooding of roadways and vulnerable structures behind protective dunes. Dangerous swimming and surfing conditions and localized beach erosion. Life threatening rip currents are likely for all people entering the surf zone.
