SPOKANE, Wash. - The National Weather Service issued a Red Flag Warning for critical fire weather in the Northern Columbia Basin as well as the Central Cascade Valleys.

NWS Spokane tweeted out the warning Sunday morning and said a Red Flag Warning means critical fire weather conditions, like gusty winds and low relative humidity, are forecast to occur. This can lead to rapid fire spread with existing fires or new fires.
