Louisiana's health department calls boil advisories for four more water districts, bringing the total to nine. Until the water is tested and found safe to drink, people there should disinfect water before drinking, cooking, brushing teeth or preparing food with it.
Late Wednesday, it issued boil advisories in West Baton Rouge Waterworks District 2 because a fallen tree broke a water main. The Alton Water System and Crossgates Ben Thomas Road in St. Tammany Parish and the town of Roseland in Tangipahoa Parihs have pressure losses caused by power outages.
Tropical Storm Isaac staggered toward central Louisiana early Thursday, its weakening winds still potent enough to drive storm surge into portions of the coast and the River Parishes between New Orleans and Baton Rouge.
Water was rising late Wednesday in portions of St. Charles and St. John the parishes, where evacuations were ordered as water poured in from Lake Maurepas and Lake Pontchartrain. In neighboring Jefferson Parish, Isaac was pushing water into the fishing village of Jean Lafitte.
