Seattle City Light crews restored electricity to an estimate 3,300 customers in the Burien/Normandy Park area, after mylar balloons caused an outage on Saturday night, Sept. 26, 2020.

The outage affected an area from around Three Tree Point/Gregory Heights on the west up to Riverton Heights on the north, and power was fully restored around 9 p.m.

However, the origin of the mylar balloons remains a mystery.
