Those gusty winds that have erupted out of nowhere the last few days are set to continue through Saturday evening, along with a couple more days of very warm temperatures. Low humidity and wind are wreaking havoc on some of the wildfires burning in Montana.

Be safe in the coming days as these weather conditions really are quite precarious. For instance, Wednesday evening: the Air Quality Index in Bozeman rose dramatically and extremely quickly from healthy levels in the 20s and 170s and 180s in a matter of 45 minutes!!! All that drama was from existing fires and gusty winds.

If you're in the back country or out camping on Saturday, consider skipping the fire altogether. The weather may change rapidly with the most concern surrounding the gusty winds. They could kick up drastically, without time to put out embers safely.
