BOISE -- A thunderstorm moved quickly through the Treasure Valley Thursday, bringing lightning strikes, rain, hail and winds gusts up to 60 miles per hour.

According to the National Weather Service, Boise received about 0.42 inches of rain during the storm. All that precipitation came down in a little more than an hour, according to KTVB meteorologist Larry Gebert.

The rapid rainfall was locally heavy in some areas, causing flash floods that swamped some cars up to their fenders.

Two-thirds of the rain we've had this summer fell yesterday, Gebert said.

The high winds ripped some trees from their roots, especially near the Columbia Village neighborhood in Boise.

The storm reached Boise around 5 p.m. and knocked down numerous power lines, according to Ada County dispatch. Traffic signals were reportedly out a quite a few intersections in Boise.

As of 11:00 Thursday night, Idaho Power had reported 5,000 customers without electricity in Boise. Another large outage of over 4,000 customers was reported in Ontario, Payette, Horseshoe Bend and Garden Valley.

  • Multiple areas around Boise
  • Powerline Road area in Nampa
  • Area of Watson Street to North Park Boulevard and from South College Green to Southwest 13th Street in Ontario
  • Area of 4th Street to 11th Street in Payette

By Friday morning, power had been restored to most areas. Idaho Power says if your power is not restored within two hours, to call the outage line at 208-388-2323 or 800-488-6151.
