...HIGH SURF ADVISORY REMAINS IN EFFECT UNTIL 8 PM EDT FRIDAY... ...HIGH RIP CURRENT RISK REMAINS IN EFFECT THROUGH FRIDAY EVENING... ...COASTAL FLOOD WARNING REMAINS IN EFFECT FROM 5 PM THIS AFTERNOON TO 3 AM EDT FRIDAY... ...COASTAL FLOOD ADVISORY REMAINS IN EFFECT FROM 5 AM TO 2 PM EDT FRIDAY... * WHAT...For the High Rip Current Risk, life-threatening rip currents. For the High Surf Advisory, large breaking waves building to 12 to 16 ft through tonight, subsiding to and 8 to 12 feet on Friday afternoon. For the Coastal Flood Warning, 1 1/2 to 2 feet of inundation above ground level expected in vulnerable areas near the waterfront and shoreline. For the Coastal Flood Advisory, up to 1 1/2 ft of inundation above ground level likely. Moderate coastal flooding potential will be highest for north facing shoreline areas along the southern and eastern bays, due to to enhanced wave action. This includes Orient Point. * WHERE...Southeast Suffolk County. * WHEN...For the High Surf Advisory, until 8 PM EDT Friday. For the High Rip Current Risk, through Friday evening. For the Coastal Flood Warning, from 5 PM today to 3 AM EDT Friday. For the Coastal Flood Advisory, from 5 AM to 2 PM EDT Friday. * COASTAL FLOOD IMPACTS...Widespread minor to locally moderate flooding of vulnerable areas near the waterfront and shoreline with this evening's high tide. Expect 1 1/2 to 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...Along the ocean front, 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 along the ocean front. Along the north shore of the south fork, 2 to 4 ft breaking waves will result in beach erosion and locally moderate flooding of shoreline roads and properties during this evening's high tide. Along the north facing shore of the barrier islands, 1 to 3 ft breaking waves will result in beach erosion and locally moderate flooding flooding of shoreline roads and properties during this evening's high tide PRECAUTIONARY/PREPAREDNESS ACTIONS... 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. && Time of high total tides are approximate to the nearest hour.
