⚠️B.C. Day Weekend Fire Weather Outlook Tomorrow: smoke clears with a trough/cold front. Critical fire risk window ~noon-5 pm. Southwest winds pick up 20-50 km/h with low RH. Valley floor stays dry; Monashee Mtns will act as a convection trigger (lightning possible), without much precip. 🌩️ #VernonBC

The Okanagan Valley will remain dry.Map showing Duff Moisture Code levels around Kelowna, Penticton, and Kamloops on 8/1/2026, mostly indicating very low moisture (red shades). The risk tomorrow (shown) is that If a lightning strike grounds into the high-Duff Moisture Code organic layers of the Monashees, it creates dangerous holdover fires that can smoulder invisibly for days before igniting.

🕛RN 🟠Vernon finally gets an air quality advisory from Environment Canada, straight to Orange, bypassing Yellow. Exposure to high smoke levels can pose threat to health regardless of age or health status. 🏥Avoid strenuous outdoor activities. Stay indoors in a space with cleaner air. #VernonBC
