The bad weather is thought to have caused two accidents in Groningen on Monday morning, in which two people died.
In one, a man was killed when his car skidded off the road and into a canal.
In the second incident, a car was involved in a head on collision with a bus.
Meanwhile, the emergency services have resumed their search for a 58-year-old man who failed to return home after a skating trip to the Nieuwkoopse lakes between Amsterdam and Gouda on Sunday.
A defence ministry helicopter and an unmanned aircraft equiped with an infra-red camera are being used in the hunt.
