The telephone number 1722 was activated on Monday evening because of the disruptive weather forecast, the Federal Public Service announced.
The line aims to ease any backlog of calls to emergency call centres on number 112 during adverse weather conditions and to not keep those whose life is in danger waiting. For all non-urgent calls to the fire brigade, it is necessary to dial the temporary number 1722.
The Royal Meteorological Institute issued a yellow alert for rainfall because up to 20 l/m2 could fall over many areas.
