Thunderstorm outlook

Human expertise, not just an algorithm

When a thunderstorm episode threatens Belgium, our forecaster analyses the models, maps the risk municipality by municipality (from no risk to very high risk) and writes a clear commentary: where, when, how intense, and what to expect (heavy rain, hail, gusts, lightning activity).

Hover over or tap the map to see the level for each municipality. For thunderstorms already under way, check the storm alerts by town and the live lightning map. The automatic thunderstorm risk, calculated continuously from the model consensus, is still available on the weather hazards page.
