Flying to the Northeast from Seattle is going to be a challenge again Tuesday.
At least 16 flights from Seattle have been canceled. The canceled flights were headed to Boston, Philadelphia, New York, New Jersey and Washington DC.
Passengers are being asked to check with their airlines before arriving at the airport.
According to the flight-tracking service FlightAware, more than 6,000 flights total were canceled on Tuesday. That brings the tally of flights canceled because of the storm to more than 15,000.
More than 500 flights scheduled for Wednesday have also been canceled.
