Idaho Power said three separate outages affected more than 5,000 customers in Boise Thursday night. One outage affected 4,751 customers, another 212 and the third turned out the lights on 138 customers.
High winds sent trees into lines, Idaho Power said.
Boise Fire Department Chief Dennis Doan tweeted at about 7:30 p.m. that firefighters had a resident safely out of a home on Adams Street after winds blew down a power line. Idaho Power was responding.
There also was a report of a power line down on North Atlantic Street in Boise.
Weather Service meteorologist Megan Thimmesch said the winds that whipped through the Valley were outflow winds from a thunderstorm that tracked northeast in Malheur County in Oregon.
Average wind speeds were 40 to 50 mph, with a peak gust of 54 mph at Boise Airport, Thimmesch said.
