NEW ORLEANS (AP) — Authorities say a storm surge driven by Hurricane Isaac is overtopping a levee in a thinly populated part of mostly rural Plaquemines Parish, south of New Orleans.
Parish spokesman Caitlin Campbell says water is running over an 18-mile stretch of the levee and some homes are flooded.
Sheriff's deputies from St. Bernard and Plaquemines parishes are going house-to-house looking for residents who'd remained after an evacuation order.
Campbell says streets in the area are still passable.
Parish President Billy Nungesser says a portion of the roof of his home on the parish's west bank has blown off. He describes wind-driven rain coming into his home as "like standing in a light socket with a fire hose turned on."
