NEW YORK (AP) -- An unusual October snowstorm along the East Coast is delaying flights at airports in the Northeast that are hubs for airlines.

The storm led to delays of up to 75 minutes Saturday afternoon at the major airports that serve New York City.

Flights headed to New York's Kennedy and LaGuardia airports or Philadelphia's airport weren't allowed to depart until early afternoon.

The snow was hitting communities inland in mid-Atlantic states the hardest, and the worst was expected later in western Massachusetts and the surrounding region.

Relatively warm water temperatures could keep the snowfall totals much lower along the Atlantic coast in such cities as Boston. Washington was expected to get just a dusting.

The National Weather Service says 1 to 3 inches of snowfall were forecast along the I-95 corridor.
