...Elevated Fire Weather Conditions this Afternoon...

The combination of low relative humidity values, warm
temperatures, southerly winds, and dry fuels will result in
elevated fire weather conditions this afternoon across areas along
and north of Interstate 90. Afternoon relative humidity values
will fall to around 15 to 25 percent with winds of 10 to 15 mph,
gusting to 20 mph.

Under these conditions, fires will start and spread easily.
Please exercise caution with any activities that involve outdoor
fires or create sparks, including campfires, grilling, and
operating large equipment. Cigarettes should be disposed of and
extinguished properly. Please heed any local burn bans.
