Belgium’s thunderstorm alert now covers almost the entire country as 1722 is activated
Updated: 27 June 2026, 00:00 UTC | Brussels. Belgium’s thunderstorm alert has been extended to the quasi totalité pays and the non-emergency number 1722 has been activated, 7sur7 reported, while the Royal Meteorological Institute forecasts locally intense storms with hail and strong gusts during the hot spell.
This is practical public-safety information. People in Belgium should secure loose outdoor items, avoid unnecessary exposure during thunderstorms, follow local instructions, and use 112 only when life is in danger. For storm damage without immediate danger, the reported activation of 1722 directs callers away from emergency dispatch lines.
The subject is a Belgian severe-weather service alert. The , ’s official weather service, says isolated and organised thunderstorms are expected around the passage of unstable hot air, with local hail and strong wind gusts. The 1722 number is used for storm-related non-life-threatening assistance so emergency lines remain available for immediate danger.
Background
uses colour-coded weather warnings through the . The lists lightning, hail, flooding, wind and storms among natural risks in Belgium, reflecting a system that separates forecast warnings from emergency response channels.
Impact
Regional — The alert concerns Belgium nationally, with practical relevance for Brussels, Wallonia and Flanders because thunderstorms can be highly local while the warning area is broad.
Local — For Brussels, Wallonia and Flanders, the practical message is the same: monitor IRM updates, secure outdoor objects, avoid sheltering under trees, and use 1722 for non-urgent storm damage if the line is active.
What it means for you
Call 112 only for immediate danger. For storm damage without danger, use 1722 when active or the online 1722 route. Move outdoor objects inside, close windows, avoid wooded areas during lightning, and delay exposed travel during storm cells.
Opposing perspectives
- Emergency services and dispatch centres
Emergency services prioritise keeping 112 clear for life-threatening situations. The reported activation of 1722 supports that goal by directing storm-damage calls, such as a fallen branch or water entering a cellar without immediate danger, to a separate non-emergency route.
- Residents, commuters and event organisers
Residents and organisers need simple, local decisions: whether to secure property, delay travel, move activities indoors or monitor radar. The broad alert means the risk is not confined to one province, but the actual impact remains local and depends on where cells develop.
