There were more than 30 planes that were diverted to other airports because of the storm that came through Western Washington, according to Sea-Tac Airport spokesman Perry Cooper.
Some planes were diverted to Paine Field, Spokane, Portland and Vancouver, British Columbia.
There was a ground stop at the airport but it was not confirmed how long it lasted.
Perry said there were no outages at the airport itself and air traffic control was not affected from an electrical standpoint.
Officials said airport crews are working with the airlines to bring those passengers who were diverted to Seattle.
