"Especially the E313 motorway between Hasselt and Antwerp is affected with some 30 vehicles involved in accidents," says Hajo Beeckman of the Flemish Traffic Centre.
Most of the accidents have been caused by cars slipping and sliding resulting in minor accidents with damage to the bodywork.
Several accidents have also taken place on the E19 motorway between Antwerp and Brussels.
Sections of the ring road around Brussels were closed off for some time during the night where several accidents also took place. Most of the accidents were not serious but there was one traffic fatality in Groot-Bijgaarden. A 25 year old woman was killed. In the centre of Liège a man was also killed.
The authorities are advising people not to drive if they can avoid it and if they cannot people should drive very slowly. Prudence is also advised on the motorways.
