BOISE, Idaho (AP) — A severe storm system crossing Idaho left thousands of customers without power. Thunderstorms moved across the state Thursday evening, and officials say there were reports of trees and power lines that were knocked down.

Idaho Power estimated a little after 7:30 p.m. that there were about 4,500 customers without power in the Boise area, 2,500 in the dark around Horseshoe Bend and another 1,600 without service in areas around Twin Falls.

Thousands of others who lost power earlier in the night had their power restored. Idaho Power says crews are continuing to work to restore service but didn't have definitive projections on when electricity coverage would return to normal.
