Current Weather

Weather Concerns

Temperatures climbed rapidly this afternoon with highs ranging from the lower 80s along the ridges above 5000 feet to the mid-90s in the valley bottoms. The humidity lowered to around 15 to 25 percent. Winds along the ridges varied through the day but were predominantly from the west to northwest at 5 to 10 mph.

The atmosphere is unstable, and the weather on Friday poses concerns for fire behavior. The instability combined with hot temperatures and low humidity may result in critical fire weather conditions.

Winds will be from the East to Northeast at 8 to 12 mph gusting to 18 mph along the ridges. Northeast winds may align and accelerate along north to south drainages such as Turkey Creek,

Panjab Creek and Meadow Creek.

Due to the upcoming change in weather, the incident meteorologist will be releasing radiosonde balloons over the next several days to capture the stability and winds aloft near the fire site.
