Thunderstorms produced heavy rain across portions of the Lower Treasure Valley, including the city of Boise. Social media, weather spotter, and emergency manager reports indicated localized flooding.
During the evening of September 11, a flash flood occurred in the foothills of the Boise Mountains. The foothills had received significant rainfall all day long. Between 500 pm and 600 pm MST a heavy shower dumped 4 tenths of an inch of rain in 9 minutes on the foothills triggering flash flooding into the north end of Boise. The wall of mud and debris was estimated at 15 feet high as it breached six flood control dams and washed over a golf course. While most of the damage consisted of mud and debris on local roadways, the golf course sustained damage and 12 houses were slightly damaged at the foundations. No injuries were reported. As of publishing , damages to roads in the city and clean up costs were estimated at at least 60,000 dollars.
Heavy rain from slow moving thunderstorms caused flash flooding in the Boise metro area. Over an inch of rain fell in less than an hour across portions of Boise. Flash flooding was reported in the downtown area and in the north and northwest parts of the city.
A strong outflow boundary from a thunderstorm damaged several power lines around the Boise metropolitan area and Garden Valley. Around 2,000-3,000 people were estimated to be without power in both of those regions due to wind damage.
The public reported a large spruce tree was knocked down along with old juniper trees. Idaho Power reported that this caused 2000 customers to be without power in the Boise North End.
Thunderstorms that moved across Ada County caused damage around the Boise area, including tree tops torn off, a large tree snapped at its base, and residential fences blown down.
Gusty winds and rain ripped through the Treasure Valley, causing power outages and knocking down huge trees. KBCI TV reported numerous trees and power lines down across the Boise metro area.
A line of thunderstorms produced wind gusts to 44 knots (51 mph) and hail up to 3/4 inch diameter from 10 miles west of Boise into the city of Boise. Numerous trees and power lines were brought down by the storm.
During the afternoon of May 3rd a thunderstorm over Boise sent a bolt of lightning onto the Crane Creek Country Club golf course. Three golfers were knocked down when a the lightening struck the ground near by. None of the golfers felt an electric shock but the explosion knocked them to the ground. Medical authorities summoned to the scene determined that there were no injuries to the golfers.
A severe weather spotter reported hail, measuring 1.00 inch in diameter, falling from a thunderstorm 7 miles north of Boise. The storm also produced heavy rains and frequent lightning that lasted for almost an hour.
