  • La Libre reported on 11 July 2026 that Belgium was placed under a yellow weather alert.
  • Forecasters warned temperatures could rise higher than initially predicted.
  • Yellow is the lowest tier in the IRM/KMI warning system (yellow, orange, red).
  • The exact affected regions and peak temperatures were not detailed in the initial report.

A yellow weather alert is the lowest of the four warning levels (yellow, orange, red) issued by Belgium's Royal Meteorological Institute (IRM in French, KMI in Dutch). It indicates potentially disruptive or locally hazardous weather and advises awareness and routine precautions. In summer it is most commonly linked to heat. La Libre reported that the current yellow alert came with a caveat that temperatures could exceed earlier forecasts.

Background

Belgium's warning system uses colour-coded tiers managed by the IRM/KMI. Heat-related yellow and orange alerts have become more frequent in recent summers, and Belgian authorities maintain federal and regional heat-wave and ozone plans that activate as conditions worsen.

Context & what happens next

What to do

Stay hydrated, seek shade during the hottest afternoon hours, check on vulnerable people, and monitor official IRM/KMI updates for changes to the alert level.

Impact

Regional — The alert was reported as applying to Belgium; the initial reporting did not specify which regions or provinces would see the highest temperatures, so residents across Flanders, Wallonia and Brussels should check localised IRM forecasts.
