One-to-two hour delays are expected to begin at about 10 a.m. today, according to airport duty manager Dan D'Innocenti.
"Early morning departures are generally not affected," D'Innocenti said. "It's going to get a little more difficult as the day progresses." International flights should not be affected by the weather, according to D'Innocenti.
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.
