Forest Fires in the United States

5 November 1999

The National Interagency Fire Center reported on 4 November 1999 that after nearly 11 weeks of firefighting efforts, the Big Bar Complex was contained yesterday. This lightning-ignited complex of fires was first detected on August 23 about 28 miles northwest of Weaverville, California. Several fires burned together creating two separate fires being managed by two incident management teams. Firefighters worked diligently to contain these fires and constructed 159 miles of fireline on the Megram fire and 35 miles on the Onion fire. For more information about the Big Bar Complex, visit the Shasta-Trinity National Forest web site. Two wildland fires continue to burn in Montana and North Dakota. The wind-driven Frontier fire near Wolf Point, Montana, destroyed six homes and 18 outbuildings yesterday, but is expected to be contained today. Fire conditions remain extreme in Montana where a red flag weather warning is posted for strong winds in the eastern portion of the state.

Fire Weather Outlook
Winds will range from 35 to 50 mph with gusts up to 70 mph in central Montana as a storm system moves across southern Canada.
A cold front will push clouds across eastern Oregon and southern Idaho today bringing scattered rain showers to the states.
High pressure will persist across the southwestern U.S. with continuing dry conditions across California.
