"Firefighters continue to battle a wildfire near Kenosha Pass today as most of the state is under an extreme fire danger warning.

The Snyder Creek fire, in Park County about three miles south of Kenosha Pass and first spotted on Sunday morning, is about 20 percent contained, said Ralph Bellah, a fire spokesman with the U.S. Forest Service.

The fire has burned about 150 acres and is moving north, driven by strong winds.

No structures have been burned by the fire and no one has been injured.

About 90 firefighters are working on the blaze today but gusty winds - up to 45 mph - have grounded air support, Bellah said.

A red flag warning on high fire danger based on strong winds, low humidly and dry timber, brush and grass lands has been posted by the National Weather Service for a large portion of the state including the southern foothills, South Park and the northeastern plains. The warning is posted through 8 p.m., the weather service said.

Humidity readings will likely be in the single digits in most areas today, and high temperatures in some areas will climb above the 80-degree mark.

The scenario has firefighters bracing for the possible break-out of additional fires.

"Please be careful," Bellah warned the public.

The weather service anticipates thunderstorms in the mountains this afternoon, but they'll likely produce more winds than moisture.

A cold front bearing down on Colorado could bring moisture and fire relief starting Tuesday night and continuing into Wednesday, the weather service said."
