DALLAS - Fitch Ratings cited Louisiana's continued recovery from the dislocations caused by the 2005 hurricanes on Thursday for upgrading the state's general obligation debt to A-plus from A and its tax-supported debt to A from A-minus.

"The state has maintained sizable financial balances and realized exceptionally strong revenue collections, bolstered by high oil and gas and hurricane recovery-related revenues, although it remains to be seen how much of the recent revenue strength is sustainable over the long term," Fitch analysts Kenneth T. Weinstein and Richard J. Raphael said. "Economic recovery is evident, though progress has been slow in New Orleans, which was most affected by the storms."
