At 3:53 p.m. on Wednesday, the National Weather Service issued a coastal flood advisory valid from Friday 6 p.m. until Saturday 2 a.m. for Suffolk and Nassau counties.

The weather service adds, "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."
