Wildfires - October 2005
Wildfire activity diminished across the U.S. during October, as the remaining large fires in the West and Rocky Mountain regions were suppressed. However, several large fires developed in the Great Plains in early November due to dry conditions in the central and southern Plains.
Typically, fire activity moves from the Pacific Northwest southward to the Southwest as the Polar jet stream shifts south during autumn. However, above normal precipitation has been observed at the beginnning of the western wet season inhibiting large fire development over the past month.
As reported by the National Interagency Fire Center, over 8.3 million acres have burned across the U.S. by the end of October, which at present ranks the 2005 season as the second worst since 1960 for total acreage burned. Currently the 2000 fire season remains the record year for the U.S. with over 8.4 million acres burned.
Alaska had its second consecutive year with widespread wildfire activity, as over 4.4 million acres have burned this year across the state. As of the end of October 2005 over 3.9 million acres have burned across the remainder of the U.S..

Dead fuel moisture levels across the western U.S. and High Plains were dry during October. In particular, fine fuel moisture levels (i.e., 10–hour fuels) remained below 5% across most western states during the past month, with the exception of the Pacific Northwest.
