Dozens of San Francisco flights to the East Coast were canceled Monday due to heavy snow storms that pounded the eastern seaboard, with blizzard conditions expected in seven states.

A total of 51 flights were canceled Monday out of San Francisco International Airport, including to New York City, Boston, Newark and Philadelphia. Most of the canceled flights were departures, airport spokesman Doug Yakel said.

At Oakland International Airport, the only cancellation was a Jet Blue flight to New York City. The Mineta San Jose airport saw little disruption due to the expected storms on the East Coast, canceling two flights — one incoming from and another bound for New York City — according to spokeswoman Cheryl Marcell.

The National Weather Service issued blizzard warnings for New York, Philadelphia, Providence and Hartford and urged travelers to stay put through the end of Tuesday in what is expected to be one of the worst snow storms in recent decades.
