A coastal flood advisory from the National Weather Service is in effect for Ocean County, New Jersey, until 2 p.m. Eastern on Thursday, Nov. 12. It began at 8 a.m. Forecasters expect up to a foot of water above ground in low-lying areas near the shore and tidal waterways.

The advisory covers both the Ocean and Coastal Ocean forecast zones. The weather service says water can reach vulnerable roads along the coast, on the bay side of the barrier islands and farther inland along tidal waterways. Some roads could close or have lanes blocked. Flooding can vary from one neighborhood to the next.

Check low roads on your route

Ocean County’s hazard mitigation plan documents past tidal flooding around Barnegat Bay. Drivers heading to the barrier islands or through bayside communities should check 511NJ for state highway conditions and look for notices from their town about local streets. Leave time to turn around or use a different route if a low road is blocked.

The weather service advises against driving around barricades or through water of unknown depth. If a vehicle is parked in a low area that usually floods at high tide, move it to higher ground if there is still a safe way to do so.
