But how does such a #storm - What? And do we get more in the future? Four questions about storms like Ciara. IJmuiden, Vlieland, Hoek van Holland. In the event of a heavy storm, the KNMI usually measures the highest wind speeds and the heaviest gusts. Chances are that Sunday afternoon and evening, when storm Ciara passes over, will be so.

1 How did Ciara originate?
“More than a week ago, weather conditions were seen above Canada, whose computer models predicted: that could lead to a big storm around the North Sea”, says meteorologist Jos Diepeveen of the KNMI. The weather for Europe, he explains, is calculated from the European Centre for Medium-Range Weather Forecasts in Reading, UK, where one of the strongest supercomputers in the world runs.


On Sunday, the storm Ciara travels over the Netherlands.
