Hoboken residents should be careful and not drink tap water without boiling it on Tuesday, officials say. The reason? A boil water advisory has been issued for Hoboken due to fluctuations in water pressure caused by efforts to stabilize service after a water main break at 18th Street & Jersey Avenue in Jersey City.

Liberty Utilities announced a voluntary boil advisory Wednesday night for all customers in Aurora, Mo., after crews fixed a broken pipe.

The water main break occurred near the city’s water treatment plant in the 300 block of East Staunton Road around 1:30 p.m.
