Seattle City Light says a gust of wind and a party tent caused a power outage that briefly knocked out power to more than 4,000 customers across Capitol Hill on Saturday afternoon.

Saturday, around 1 PM, near Belmont at Republican, a canopy tent was reported on wires after falling from a nearby building. A City Light crew was dispatched and electricity was quickly restored to thousands with the final 1,000 back in power by 5 PM.

CHS has reported on a variety of causes for Hill blackouts over the years.

Typically, wind, rain, and branches are the culprit. Sadly, more than a few birds have set down in the wrong place and left blocks without power over the years. These balloons, however, were innocent.

City Light didn’t say how the canopy ended up on the wires but a reliable CHS reader — the best kind — reports that a neighbor in a nearby building had been planning a rooftop dog birthday party that afternoon.

We’re glad nobody was injured and we hope the dog enjoyed the memorable marking of its birthday.
