Belgium’s meteorological office (IRM) has issued a fresh winter-weather advisory for 18 February 2026, forecasting snowfall across the Ardennes and parts of southern Wallonia from Wednesday afternoon through the evening. While Brussels and Flanders are expected to see mostly rain, gusts of up to 60 km/h could still hamper traffic on the E411 and E42 motorways and slow runs on the Brussels-Luxembourg rail corridor.
SNCB/NMBS has activated its ‘cold-weather’ timetable for the Namur-Arlon line, trimming the frequency of local trains to create buffer space for de-icing stops. Logistics operators serving Liège Airport and the nearby Trilogiport inland terminal report that last-mile deliveries may be postponed until Thursday morning if accumulations exceed five centimetres. Brussels Airport says it does not expect runway closures but warns that regional coach transfers could face delays.

If you or your staff are travelling to Belgium during this period, VisaHQ can streamline any urgent visa or travel-document needs. Our online platform (https://www.visahq.com/belgium/) offers real-time guidance, electronic applications and courier services—helping travellers adjust plans quickly when weather disrupts schedules.
Companies with field-service engineers or sales teams driving to the south should allow extra travel time and monitor live traffic feeds. HR policies that treat weather disruptions as authorised absence may need to be communicated proactively, especially for cross-border commuters from Luxembourg and northern France. Travellers connecting in Brussels to Eurostar services should also watch for knock-on effects, as high winds sometimes trigger speed restrictions in northern France.
The IRM notes that temperatures will fall to between –1 °C and 3 °C overnight, raising black-ice risks during Thursday’s morning commute. Road-salt stocks are adequate, regional authorities say, but municipal crews will prioritise main arteries before secondary roads. Mobility experts remind employers that Belgium’s rules on telework flexibility during ‘code yellow’ weather alerts allow same-day work-from-home authorisations without prior contractual amendments.
