MANTOLOKING - The Jersey Shore remains vulnerable as crews are working overtime to help restore the dunes before another winter weather system moves through.

Water was free-flowing from the ocean to the bay in seven areas along the dunes in Mantoloking both Wednesday and Thursday after this week's nor'easter.

The temporary dunes were built after Sandy to offer some protection, according to Mantoloking's Office of Emergency Management Coordinator. Borough officials say Saturday's snowstorm is not expected to be a wind event damaging to the coast, but they are taking the necessary precautions.

The borough says a long-term fix would include rebuilding the dunes with geotube technology. The same system was used in Beach Haven, where the dunes were kept intact during Sandy.

Mantoloking remains open only to residents and contractors during the day.
