.... and it really has !

28 mm rain at Brussels Uccle overnight and 23 mm at the Airport.

Many places in Belgium have had over 20 mm overnight and some much more,
e.g. Semmerzake (near Ghent) 31 mm, St Hubert in the Ardennes 32 mm,
Chièvres (near Mons) 45 mm.

Some amateur sites: Koekelare (SW of Bruges) 38 mm, Bonheiden (NE of
Brussels) 43 mm, Putte (NE of Brussels) 51 mm, Ransberg (east of Leuven)
65 mm.
