Brussels Environment has decided to close its parks as of Tuesday 9pm due to the possibility of strong storms. An update will be made this Wednesday around noon.
The Royal Meteorological Institute of Belgium (RMI) is also issuing a yellow warning across all of Belgium for storms that could break out on Wednesday. In Brussels, this warning period extends from 6am to midnight.
Although some thunderstorms may occur in isolation this Tuesday, it is primarily from Wednesday morning until evening that more structured and widespread thunderstorms are forecast; these may in turn be accompanied by heavy rainfall and strong gales. Hail is also possible, the RMI reports on its website.
