The combination of high winds and low humidity in Eastern Oregon will lead to dangerous fire conditions Sunday afternoon through Monday night.
The National Weather Service has issued a red flag warning to begin 2 p.m. Sunday for much of Umatilla County, including Pendleton and Hermiston, as well as Morrow County, Walla Walla, the Tri-Cities and much of central Oregon.
Winds are expected to gust up to 35 mph with humidity dropping to as low as 12 percent, causing any fires that develop to spread rapidly. Temperatures will reach the mid-90s Saturday and high 80s on Monday.
Outdoor burning is not recommended, according to a release from the National Weather Service office in Pendleton.
