ALLENTOWN, Pa. (CBS/AP) — Officials have issued a boil water advisory after a large water main break flooded a neighborhood in Allentown, prompting evacuations and partially swallowing a vehicle, authorities said. Allentown police said the water began rushing down the street at about 12:45 p.m. Wednesday, prompting evacuations and requests for residents to move their cars.

Lehigh County Authority Director Liesel Gross said crews were trying to shut off the 30-inch high-pressure line that serves large portions of the city and surrounding communities.

The break happened at 17th and Walnut Streets.
