Winds estimated to be 65 miles per hour based on nearby observations caused damage to a non-profit camp in McCall. A large pine tree estimated to be 150 years old topped onto a camp building constructed in the 1970s. Trees also fell onto camp equipment which will need to be replaced. Costs estimated at 150-200 thousand dollars.
A weather disturbance rotating around a cut-off low pressure system in the southwestern United States, produced thunderstorms over southwest Idaho. The winds produced by these thunderstorms were strongest in the vicinity of Cascade, 60 miles north of Boise. Trees as big as four feet in diameter were uprooted. Many of the trees fell over power lines, creating power outages.
Our COOP observer in Yellowpine observed over 100 trees down on the road from Landmark, Idaho to Yellowpine. This is a remote wilderness road used mainly by rangers, locals, and recreators, and likely took some time to clean up. Based on number and type of trees winds estimated to be 70 miles per hour.
