The IRM warning was put in place on Wednesday evening at 23:00 and will remain in place until late morning in Brussels, Wallonia, and Hainaut, and until 17:00 in Liège, Namur, and Luxembourg.
Translation of tweet: "Warning for slippy roads from 25 January at 23:00 until 26 January at 17:00: Tonight (Wednesday evening), precipitations will start at the coast before spreading over the western part of the country."
The organisation has urged caution throughout the day, with further sub-zero temperatures forecast for Friday and the weekend.
