MOONACHIE, N.J. — New Jersey Gov. Chris Christie says the sudden middle-of-the-night flooding of two towns was the result of a tidal surge that sent water overflowing a natural berm.

The governor says the surge hit the Hackensack River.

He says hundreds of people have been rescued from the low-lying towns of Moonachie (moo-NAH'-kee) and Little Ferry.

Residents of a Moonachie mobile home park say water overflowed a nearby creek when the tidal surge occurred. In Little Ferry they say water gushed out of storm drains.

Local and county officials initially reported a levee had broken, but the governor says that was erroneous.
