With temperatures soaring in the triple digits, the National Weather Service in Seattle issued a Red Flag Warning for Lewis County and other areas of Western Washington on Sunday.
The advisory will initially last from 11 a.m. to 8 p.m. Monday.
A Red Flag Warning means that critical fire weather conditions are either imminent or occurring. Any fires that develop will likely spread quickly. Outdoor burning is not recommended, and in Lewis and Thurston counties, among others, it is currently banned.
“A dry and unstable air mass with warm temperatures can contribute to active fire behavior,” the weather service wrote. “In Western Washington, significant growth on existing fires takes place under such conditions. If a fire were to begin, air quality may diminish in the surrounding area.”
The Red Flag Warning also includes parts of King, Pierce and Skamania counties.
