POMONA, N.Y. — A New York county has purchased water-filled flood barriers as tropical storm Hermine (her-MEEN) heads up the East Coast.

The Journal News (http://lohud.us/2bT9xTY ) says Rockland County bought 21 of the orange barriers at a cost of $150,000. They cover a total area of 630 feet.

The barriers look like long water bags. They’re reusable and can be filled in minutes — much faster than setting up sandbags.

The barriers can be filled from a fire hydrant, any water pump or by the flood waters they are trying to divert.

County Executive Ed Day says they can be used as a “rapid response” to rising waters and save people’s homes.

Gov. Andrew Cuomo on Friday activated the state Emergency Operations Center, which will begin on Sunday.
