URGENT - FIRE WEATHER MESSAGE
National Weather Service Spokane WA
648 AM PDT Sun Aug 24 2025

...HOT, DRY, AND UNSTABLE CONDITIONS FOR MONDAY AND TUESDAY...

.A strong ridge of high pressure will bring a period of hot and
dry conditions to the central and northern Cascades of Washington
early into the week. The ridge will shift east of the Cascades
early next week with the atmosphere becoming more unstable at that
time. Increased instability with hot and dry conditions will
bring the potential for critical fire weather conditions. In
addition, we are monitoring the potential for isolated
thunderstorms on Monday and Tuesday afternoons that could result
in new fire starts.
