Monsoon rains Monday provided some relief for two large wildfires in Southern Arizona.

The W 2 Fire, which has scorched about 530 acres along the international border nine miles east of Nogales, Ariz., was 95-percent contained Tuesday afternoon, Gerry Perry, a spokesman for the Coronado National Forest, said in a news release.

The Prison Fire, adjacent to Molino Basin in the Santa Catalina Mountains, has burned 240 acres and is 50 percent contained as of Tuesday afternoon, Perry said. Two crews, a helicopter and two water tenders remain assigned to the blaze as crews continue to monitor the perimeter and mop up. Full containment is expected in the next 24 to 48 hours.
