Power went out in much of Seattle’s South End just after noon Wednesday due to “significant” damage to the electricity distribution system.

More than than 11,000 customers were affected, according to Seattle City Light’s website.

About 3,200 customers in First Hill and the Chinatown-International District regained power by 1:45 p.m. By 2:30 p.m., another approximately 1,000 more customers had power, but crews were still unsure of the outage’s cause.

By about 3:30 p.m., about 5,500 more customers in South Seattle had power back on. That left about 1,400 customers in Beacon Hill waiting, with an estimated restoration time of 4 p.m. that Seattle City Light’s Twitter account noted was “subject to change as crews reassess remaining repairs.” City Light had no update by 5 p.m.
