Wildfires Continue to Blaze Near Washington-Oregon Border in Early October

USA – October 1st, 2012

Although wildfire season in the western and northern USA usually comes to a close in October, through September lack of significant precipitation inputs have led to above normal availability of fuels for wildfires across most of the northern half of the U.S. as well as California.  Here, wildfires can be seen burning near the Washington-Oregon border (click here for previous images).

Normally during this time of year fuels conditions would decline fairly rapidly across the northern tier.  This season, however, is seeing a very slow decline in nearly all fire danger indices, with that decline coming mostly in response to longer and colder nights.  In order for any significant improvement in fuel conditions to take place a sustained input of moisture would need to occur.  However, this seems unlikely at least through the middle of October.

Smoke from a fire in Colorado, located about halfway between Denver and Colorado Springs, fans out and billows in a northeasterly direction, contributing to a larger, smoky haze over the western United States of America (click here for previous images).

USA – September 3rd, 2012

Smoke from fires in western USA enters the crevices of valleys and rivers between mountain ridges. The western fire season continues, with over 7 million acres by the end of August. While the number of fires is down from the 10-year average of 54,209, the acreage affected is well above the average of 5.4 million acres. The fires have been quite large, particularly in Idaho and Montana, and the cost to fight them continues to rise (click here for previous images).
