The KNMI weather centre is warning of extreme weather in the north east provinces following icy conditions that led to a rash of accidents during the morning.

It is expecting the situation to gradually improve but low temperatures mean black ice may form again this evening, the KNMI said.
The warning is in force for the provinces of Groningen, Friesland, Drenthe, Flevoland, Overijssel and Gelderland.
Accidents
There were so many accidents in the Veluwe region of Gelderland this morning that the ambulance service advised people to call family, neighbours or friends to take them to hospital so they would have ambulances available for any life-threatening situations.
In Eindhoven, the police advised motorists, cyclists and pedestrians to stay at home.
