Thousands are out of power and all flights leaving Seattle-Tacoma International Airport and Boeing Field were grounded for several minutes Monday as Western Washington was buffeted by strong winds and heavy rainfall.

The grounding at Sea-Tac Airport also affected flights already in the air — they were asked to delay their landing for about 15 minutes, according to the FFA’s website. Departing and arriving flights are expected to continue experiencing short delays, the website says.
