* WHAT...For the High Surf Advisory, large breaking waves of 5 to 9 feet in the surf zone. For the High Rip Current Risk, dangerous rip currents. For the first Coastal Flood Advisory, up to one half foot of inundation above ground level expected in vulnerable areas near the waterfront and shoreline. For the second Coastal Flood Advisory, up to one foot of inundation above ground level expected in vulnerable areas near the waterfront and shoreline. * WHERE...Southwest Suffolk and Southern Nassau Counties. * WHEN...For the High Surf Advisory, until 8 PM EDT this evening. For the High Rip Current Risk, through Saturday evening. For the first Coastal Flood Advisory, until 1 PM EDT this afternoon. For the second Coastal Flood Advisory, from 6 PM this evening to 2 AM EDT Saturday. * COASTAL FLOOD IMPACTS...Widespread minor flooding of vulnerable areas near the waterfront and shoreline with this evening's high tide. Expect 1 to 1 1/2 ft of inundation above ground level in low lying, vulnerable areas. This will 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. * SWIMMING IMPACTS...Life-threatening swimming and surfing conditions and localized beach erosion. Life-threatening rip currents are likely for all people entering the surf zone. Anyone visiting the beaches should stay out of the surf. Rip currents can sweep even the best swimmers away from shore into deeper water. * SHORELINE IMPACTS...The threat for dune erosion and beach flooding will increase with successive high tides thru Fri morning. Widespread areas of dune erosion with localized overwashes are expected during the Thu evening and Fri morning high tides.

Take the necessary actions to protect flood-prone property. If travel is required, do not drive around barricades or through water of unknown depth. Inexperienced swimmers should remain out of the water due to dangerous surf conditions. If you enter the surf zone, always have a flotation device with you and swim near a lifeguard. If caught in a rip current, relax and float, and do not swim against the current. If able, swim in a direction following the shoreline. If unable to escape, face the shore and yell or wave for help.
