NEW ORLEANS (AP) - The Army Corps of Engineers has closed a gate on a suburban canal as heavy rains soak flood-prone New Orleans.
Mayor Ray Nagin shut down City Hall early, and schools also closed. People have been asked to stay indoors until the flood threat is over.
Eight inches of rain has fallen in parts of the city, and more is expected overnight.
The corps has worked to strengthen the canal as part of new safety guidelines implemented after Hurricane Katrina. But engineers worried that driving water into its walls might lead to flooding.
The area around the canal, five miles from downtown, includes homes and businesses.
