Summary | Forecast and Safety & Resources | Monitoring & Reporting 

A combination of strong, gusty winds, low relative humidities, and several days of record warmth will raise fire danger once again Sunday and Monday, mainly in the lower elevations east of the divide. A Fire Weather Watch is in effect for the lower elevations of Fremont, Johnson, Natrona, and Sweetwater Counties Sunday and Monday. Any fires that are set may quickly become uncontrollable.  We have already received reports of some field burning activites going beyond their planned boundaries this month, please use caution when working with fire and feel free to call us before you burn.

Even though it is not yet "fire season," don't let the calendar fool you. Early season wildfires can happen, especially now before green up.

There will be a few more days of dry and windy weather ahead of a major change in the weather pattern early next week.

Minimum relative humidities will be in the mid teens and low twenties through Monday east of the divide. Relative Humidities will recover late on Monday as a strong cold front pushes through.

Wind speeds will be elevated across the "wind corridor" from Rock Springs to Casper and over higher elevations, especially Sunday and Monday. Low lying vegitation remains very dry so caution while burning outdoors is still advised due to the strength of the anticipated wind speeds. 

Temperatures have been quite warm over the past two weeks. This has has aided in drying out the lower elevations. Temperatures will remain unseasonably warm through Monday.  Record highs are likely especially on Sunday. Check out the latest Forecaster Discussion for more on this storm.

 In Summary, conditions will remain dry and windy through Monday, with the most critical conditions ocurring during the afternoon hours. Winds will remain elevated, especially along the "wind corridor" - roughly, Rock Springs to Casper.  Sunday and Monday are definitely "watch out" days for burning east of the divide. These days will be very dry and windy.
