Snowstorm hits U.S. East Coast, air traffic affected

A snowstorm moving through the Northeast today is likely to trigger air traffic delays in Boston (BOS), the New York area (EWR, JFK, LGA) and Philadelphia (PHL), with runway and even airport closures possible. On the West Coast, low clouds have led to delays in Los Angeles (LAX) and also may slow flights in San Francisco (SFO). (FAA air traffic info)
