Dive teams relaunched the search of a partially frozen New Jersey lake Tuesday morning for two missing teenagers who were walking boats and fell through ice on Monday night.

Police said that the two teens fell through the ice at Budd Lake in Mount Olive Township in Morris County.  As of 9:30 p.m. Monday night, the search was called off.  Police believe the teenagers fell through the ice around 6:19 p.m., ABC News affiliate WABC-TV reported.

"So far we have been unable to find anyone at this time, but continue to search as conditions allow throughout the night," a police spokesman told ABC News overnight.  No details on the victims were immediately available.

The incident at Budd Lake is the latest in a winter that has seen numerous accidents on lakes across the U.S.  Earlier in the day Monday, halfway across the country in Wisconsin, eight fishermen had to be rescued from an icy floe in the bay of Green Bay when high winds caused the ice to break free.

On Sunday, a woman was caught on camera clinging to the ice on the Maumee River in Toledo, Ohio.  She floated in the bone-chilling waters for an hour before first responders pulled her to safety.

Experts say unseasonably warm temperatures have caused a January thaw from coast to coast, leaving usually thick ice dangerously thin.

"If you fall through the ice, a life jacket will keep you afloat and reduce the hypothermia affects," Paul Segura with the U.S. Coast Guard said.

Still, experts say cold water kills quickly making these situations not only dangerous, but often deadly.
