SEATAC, Wash. — A portion of Seattle-Tacoma International Airport closed Tuesday due to flooding.
Airport officials discovered “a large flood of water” early Tuesday morning in the south portion of Concourse A, according to a Sea-Tac Airport spokesperson. Employees closed off the area and stopped the flow of water.
The flooding was caused by part of the sprinkler system being opened, which a contractor believed was out of operation, the spokesperson said.
In video shared on Twitter, travelers could be seen trying to skirt a large puddle of water that extended across the walkway from businesses to the seating area next to gate A11.
Two of the three gates that were impacted reopened Tuesday, and the third gate reopened Wednesday morning.
The spokesperson said there was “no noticeable impact” to operations outside the impacted area. However, flights that were supposed to leave from the affected gates were moved during the flooding.
Concourse A is located in the southeast corner of the airport and serves airlines including United Airlines, JetBlue and AirCanada, according to the Port of Seattle website.
