NEWARK, N.J. — Officials say New Jersey and New York residents should not be alarmed if they hear sirens near port facilities.

The Port Authority will conduct a routine test of emergency systems at the New Jersey Marine Terminals in Newark and Elizabeth between noon and 2 p.m. Friday.

Sirens also will sound at the New York Marine Terminals in Brooklyn between 10 a.m. and noon on Tuesday, Nov. 15.

The sirens could be heard up to a mile away.

The federal government requires the tests.
