Schiphol airport is warning passengers that flights will be delayed or cancelled on Friday because of a westerly storm.

Dutch flag carrier KLM said on Thursday evening it had cancelled 100 return flights as a precaution, after the KNMI weather bureau issued a code yellow weather warning for the west of the country.

‘We know now that not all the flights will go ahead,’ a spokesman told broadcaster NOS on Thursday evening. The cancelled flights are for European destinations and passengers will be booked on other flights, the spokesman said.

The KNMI expects winds of up to 85 kph to batter the mainland on Friday morning, but says they will be stronger over the Wadden Sea area.
