The red flag warning is now in effect until 10 PM MDT Monday for gusty winds and low relative humidity across much of western Utah. This warning includes fire weather zones 420... 434... 439... and 435 below 7000 feet.
Southwesterly winds of 15 to 25 mph with gusts in excess of 30 mph will continue across much of western Utah this afternoon and early evening. A lull in severe fire conditions is expected tonight and Monday morning as winds decrease with sunset and humidity levels increase. A cold front will drop southeast across northern Utah Monday and into central Utah Monday evening. Gusty southwest winds which develop ahead of the front midday Monday will become northwesterly with time as the front moves across the area. These winds... when combined with very dry airmass settling across the region... will result in critical fire weather conditions across much of western Utah again Monday afternoon and evening. These winds across expected to gradually diminish after sunset Monday.
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 will create explosive fire growth potential.
