Windstorm knocks out traffic lights on Eagle Road, downs power lines and tree limbs across Boise

A windstorm swept through Boise Tuesday evening, causing traffic headaches and downed limbs.

The strongest gust reported was 48 mph at the Boise Airport, but the storm caused much more mayhem than the winds of up to 61 mph that were reported during a brief rain and windstorm late Monday afternoon, the National Weather Service and Ada County Dispatch report.

The storm peaked about 6:30 p.m. Downed trees and tree limbs were reported Downtown and across Boise, a downed power line is the suspected cause of a grass fire off Victory and Meridian roads, and a power outage turned the busy intersections of Eagle Road at Fairview and Locust Grove into temper-fraying four-way stops, a dispatch supervisor said.

Tuesday's storm didn't bring the downpour Boiseans saw Monday, but it did cause "a rather spectacular sandstorm" near the airport, National Weather Service meteorologist Joel Tannenholz said.

Tuesday's heat hit a high of 102, tying a record set last year, Tannenholz said. But Wednesday's forecast high of 100 poses no danger to that day's record of 105, set in 1898.

Scattered afternoon and evening thunderstorms are expected through the week, Tannenholz said, but Wednesday's storms are mostly expected to stay east of Boise.
