We had a holiday in Mojacar, during the night it thundered and lightened on scale I have not seen in the UK......but it never rained in Mojacar.
But it must have rained up in the hills,as the next morning there was a 10ft deep rut where the stream ran into the sea.
Just started to rain here, BSB & WSB on tele, may venture into the shed later, remove the topbox mounting bracket, ugly piece of steel when no box is fitted.
