Posted in FeatureTagged , , , , ,

Warm and dry conditions coupled with gusty westerly winds will create hazardous fire

Okanogan, Methow, Chelan and Wenatchee Valleys
* Winds: West 10 to 20 mph with gusts up to 25 mph.
* Relative Humidities: 12 to 22 percent.

Weather Service office’s warning area based on the local vegetation type, topography ,
and distance from major water sources. They usually include the daily vegetation
moisture content, expected afternoon high temperature and afternoon minimum relative
