Wildfires can spread quickly — by the time one is nearby, you may not have much time. Have an evacuation plan, and prepare an emergency supply kit ahead of time. Listen to local officials for emergency information and any evacuation orders.

Extreme winds were observed across eastern Colorado yesterday, with numerous wildfires growing quickly in Yuma County last night. The strongest winds were in the foothills, with several reports of gusts over 100mph. But the >80mph gusts on the eastern plains are perhaps even more unusual. #cowx

Chance of winter weather could end a dry spell for the Front Range and add to the state’s snowpack
It's been a quiet fall across Colorado with little to no moisture in many places. That could soon change with increased chances of winter weather.

“Some of the smaller, more local reservoirs saw significant improvement,” said Peter Goble, a climatologist for the Colorado Climate Center at Colorado State University. “If we look at our reservoir giants, like Powell and Mead, unfortunately at that scale this is kind of a drop in the bucket.”

The October floods in Colorado damaged homes and upended lives, but there was one silver lining: The water also replenished reservoirs.
