After receiving several calls Tuesday afternoon from citizens concerned about the hazy conditions, the Durango Interagency Fire Dispatch Center would like to reassure the public that no fires have been detected in southwest Colorado. 

A U.S. Forest Service reconnaissance flight this morning detected no fires, and an afternoon flight will be launched to verify there are no fires.  The weather report for southwestern Colorado calls for high clouds and high humidity, with prevailing winds from the west. 

There are large fires in Washington, Idaho, Nevada and Northern California.  One fast-moving wildfire in central Washington has burned at least 60 homes and forced hundreds of people to flee — one of several blazes scorching the West on Tuesday, threatening communities, sending up thick plumes of smoke and disrupting activity in national parks.

Fire commanders estimate the Washington blaze has burned at least 24,000 acres — about 38 square miles — since it started Monday afternoon east of the small town of Cle Elum.

In Utah, a lightning-sparked fire consumed about 34 square miles, threatened a herd of wild horses and shut down the historic Pony Express Road in the state's western desert.

In Northern California, crews made progress against an aggressive blaze in Lake County that grew to more than 9 square miles and destroyed three buildings.
