BATON ROUGE, La. (AP) - Lightning from a thunderstorm has sparked a wildfire in southwest Louisiana on the Sabine National Wildlife Refuge. The blaze is located within Management Unit 1 or waterfowl hunt unit E, located in the north-central portion of the refuge. The area is bordered on the east by Back Ridge canal, the south by Central canal, the west by Beach canal and the north by open water. Authorities say about 2,342 acres burned Wednesday through Friday in the southeastern part along Back Ridge. The U.S. Fish and Wildlife Service said Saturday that the fire has been contained and is not a threat to any facilities. Less than 50 acres remain on fire. A crew of six federal firefighters is in place to monitor the fire throughout the weekend and into next week.
