Philadelphia flights cancelled in East Coast storm

The major winter storm heading toward Pennsylvania was already leading to travel disruptions Friday, as flights were delayed and cancelations announced.

All flights into and out of Philadelphia International Airport have been canceled for Saturday, when the blizzard conditions were expected to be in full swing, airport spokeswoman Diane Gerace said.

The storm on the East Coast is causing flight delays at local airports. As of 6:30 a.m. more than 20 departing flights were delayed at SFO, and two cancelations along with one delay were reported at Oakland. 

"The airlines got out in front of this storm and proactively canceled all flights," Gerace said.

She said airlines hope to resume flights into and out of Philadelphia on Sunday, but travelers should check with their carriers to get detailed information.

Departing flights were already delayed by as much as 30 minutes at the airport Friday morning, according to the website Those delays were expected to get longer later in the day.

The National Weather Service on Friday issued a blizzard warning for Philadelphia and its northern suburbs.

Snow is expected to start falling after 7 p.m. Friday and won't slow down until Sunday around 10 a.m. As much as 18 inches could fall around Philadelphia, and two feet is possible for inland places like Gettysburg.

Gov. Tom Wolf declared a state of emergency ahead of the storm, which allows authorities to respond quickly to any problems.

Amtrak's Keystone Service between Harrisburg and New York will have a modified schedule with fewer trains.
