In North Somerset, it became very, very grey late afternoon yesterday. Then - in the distance - heard the first thunder. A short while later it started to rain, then as the storm grew nearer the rain battered down, actually causing flooding. Thunder and Lightening (Yes, very very frightening). I kept the patio door on my balcony open throughout (the overhang from the balcony on the next floor gives protection). Lots of water came down, lasted about then rather scary minutes before it started to move away Eastwards.
