PRECAUTIONARY/PREPAREDNESS ACTIONS…

A Red Flag Warning means that critical fire weather conditions
are either occurring now….or will shortly. A combination of
strong winds…low relative humidity…and warm temperatures can
contribute to extreme fire behavior.
Cooling temperatures are expected Sunday as a strong cold front
pushes south across the area, which will help ease fire danger
levels. Light rain is expected across much of the area Sunday
afternoon and evening with light snow possible in the mountains.
Snow levels will be lowering to near 8000 ft by late afternoon north
of I70, continuing south through the evening over areas south of
I70. Snowfall accumulations will be less than one inch and travel
impacts should be very minimal. No hazardous weather is expected
Monday through Thursday.
