More than 100 flights were canceled, with scores more delayed, at San Francisco International Airport Sunday, due to high winds and low visibility from the all-day rainstorm.

Average delays at SFO were running about four-and-a-half hours by the early afternoon said Sean Miyaki, the airport’s duty manager.

In all, 123 flights were canceled and another 182 were delayed, he said, with more possible as the day went on. Mostly all weather-related, the delays were mounting because of the “dark and cloudy” conditions that made it difficult for pilots to see, Miyaki said.

“It’s windy, I’ll tell you, windy and wet,” Miyaki said.

Hangups on the East Coast could have contributed to SFO’s issues, as a large winter storm Saturday caused hundreds of cancellations at airports from Philadelphia to Boston, with delays that lingered into Sunday.

“We’re all dealing with the weather, man,” Miyaki said.
