The National Weather Service has issued a “red flag” warning, effective through 9 p.m. Friday, for the Columbia Basin.
High heat, gusty winds and low humidity have created critical fire danger conditions, the weather service said.
Benton County Fire Marshal Ken Williams advises that all burning is prohibited, and all current fires must be immediately extinguished — including emergency agricultural burning.
Winds will remain at 15 to 25 mph into Friday afternoon before decreasing Friday night and Saturday. Sunday will bring westerly winds of 10 to 20 mph.
