A mix of snow and ice bore down on the US north-east early on Saturday, disrupting post-holiday weekend airline traffic and prompting officials in New York and New Jersey to issue weather emergency declarations even as the storm ebbed by mid-morning.

More than 14,400 domestic US flights on Saturday were canceled or delayed as of mid-morning, with the majority in the New York area, including at John F Kennedy international airport, LaGuardia airport and Newark Liberty international airport, according to the tracking site FlightAware.
