The weather is continuing to cause problems at Amsterdam’s Schiphol airport and dozens more flights have been canceled on Tuesday, a spokesman for the airport said. 

In addition, the airport is still dealing with the aftermath of a 2.5 hour technical problem with the air traffic control system on Monday night which led to all takeoffs and landings being cancelled. 

“The knock-on effect of last night and this morning’s weather have had an impact,” the spokesman told broadcaster NOS. Two of the airport’s seven runways are currently in use. 

In total, 90 flights were cancelled on Monday, most of which were within Europe. 

It is not yet clear why the air draft control system went down but most flights were able to deviate to other airports. Take-offs were also delayed but the impact was limited because the problems occurred in the late evening.
