Description
What
For the High Surf Advisory, large breaking waves of 8 to 11 feet in the surf zone. For the High Rip Current Risk, dangerous rip currents. For the Coastal Flood Watch, two to three feet of inundation above ground level possible in vulnerable areas near the waterfront and shoreline.
Where
Southeast Suffolk County.
When
For the High Surf Advisory, until 8 PM EDT Saturday. For the High Rip Current Risk, through Saturday evening. For the Coastal Flood Watch, from Friday afternoon through Saturday morning.
Impacts
Late Friday afternoon into early Saturday, widespread flooding of vulnerable areas near the waterfront and shoreline, including roads, parking lots, parks, lawns, and homes and businesses with basements near the waterfront. Numerous road closures are likely, and vehicles parked in vulnerable areas near the waterfront will likely become flooded. Flooding will also extend inland from the waterfront along tidal rivers and bays. Through Saturday early evening, dangerous 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.
Additional details
Beach flooding and erosion likely Friday into Saturday.
Instructions
If travel is required, allow extra time as some roads may be closed. Do not drive around barricades or through water of unknown depth. Take the necessary actions to protect flood-prone property. 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.
