Most flights arriving at San Francisco International Airport have been delayed up to two hours today due to rain, according to an airport duty manager. The delays began at about 9 a.m. and are expected to last through the day and possibly into tonight.

Departing flights are not being impacted as much as the arriving ones, airport duty manager Douglas Lyon said.

Flights departing from the Oakland International Airport are delayed on average by about 10 to 15 minutes, most likely due to weather, airport spokeswoman Rosemary Barnes said.

Weather may cause longer delays in Oakland later today as well, according to Barnes.

“With the wind and the rain that we've been experiencing this morning, (delays) are always a possibility,” Barnes said.

Flights at Norman Y. Mineta San Jose International Airport are not expected to be delayed today, according to airport spokesman David Vossbrink.

“It's wet … but it seems like a normal winter storm with nothing unusual that will affect our operation, Vossbrink said.

Travelers are advised to check their flight status before heading to Bay Area airports today.

Around 2 to 3 inches of rain are expected throughout the Bay Area today and Saturday, and the mountains could get 5 or more inches of rain through Saturday, according to Steve Anderson, a meteorologist for the National Weather Service.

The storm is expected to last through Saturday,Anderson said.
