Francine updates: Storm pushes across South as tropical depression

Thunderstorms across Louisiana are producing heavy rain across the state, according to the National Weather Service.

Flash Flood Warnings are in effect for "Northwestern Jefferson Parish, Southwestern Orleans, Northern St. Charles Parish and Southwestern St. John The Baptist Parish" until 11:45 PM local time, the NWS said Wednesday evening.

Between 5 to 7 inches of rain has already fallen in the areas, with an additional 2 to 3 inches expected, according to NWS.

Other areas in Louisiana that may experience flash flooding include Hahnville, Metairie, Avondale, Laplace, Marrero, Reserve, Harvey, Timberlane, Jefferson, Gretna, Harahan, Westwego, St. Rose, Destrehan, Ama, New Sarpy, Norco, Luling and Waggaman.

AT&T and T-Mobile say the issues customers in New Orleans had reported in reaching 911 services in some storm-impacted areas have been resolved.

Those customers who needed emergency services were told to call the 10-digit number instead -- 504 671-3600 -- according to the NOLA Ready Emergency Alert System.
