SAN FRANCISCO —

A string of disruptive weather conditions has forced a ground delay at San Francisco International Airport on the tail end of the holiday weekend.

Beginning at 10:45 a.m. Monday, the Federal Aviation Administration enacted a ground stop at SFO caused by low-ceiling clouds. The average delay time is 30 minutes, but travelers could experience delays lasting almost an hour and a half.

SFO is “dealing with some southwesterly winds which can be impactful as well, but the ground stop is due to low ceilings, so, with that, we are expecting that to persist,” National Weather Service forecaster Dalton Behringer told SFGATE.

As of 1:30 p.m. on Monday, 211 flights have been delayed, according to FlightAware.
