Rain and low clouds are causing flight delays of up to an hour at San Francisco International Airport Tuesday, an airport duty manager said.

Bad weather in the Bay Area and in the Northeast is delaying some arriving flights by about 45 minutes to an hour, duty manager Chuck Navigante said.

Some departures are about 30 minutes behind schedule, Navigante said.

“We urge everyone to check with their individual airlines because some flights are still leaving on time,” Navigante said.
