Nearly 5,000 West Seattle homes and businesses lost power Tuesday evening after a summer storm rolled through the Seattle area, dumping rain and causing dozens of lightning strikes, officials said.
The outages were first reported before 5:30 p.m. between Alki Avenue Southwest on the north, Southwest Holly Street on the south, 31st Avenue Southwest on the east and Puget Sound on the west, according to Seattle City Light.
By 6:45 p.m., about 3,200 customers were out of power.
The storm moved quickly from the southwest across the Puget Sound, weakening as it went, said Josh Smith, a meteorologist with the National Weather Service in Seattle.
At least 66 cloud-to-ground lightning strikes had been reported as of 6:15 p.m., Smith said.
Storms like this can be common this time of year, he said.
The National Weather Service is forecasting a high of 71 degrees for Wednesday, with rain showers likely.
