My friend's wife, who is from Jerez brought this to my attention n New
Year's Eve. She said her mother had never seen rain like it and that
the local car park - which is a long way from a river - had floodwater
reaching past saloon cars' wing mirrors

They talk in terms of litres of rain - does anyone know what this is
in standard mm?
