Some torrential rain & thunder along the whole of the south Cornwall coast, set off by the onset of sea breeze. Normally it's a north coast even, as the north coast sea breeze meets a light humid S-SE gradient wind. A bit unusual for a northerly to be so humid. Anyway, here's the radar
Dry in Penzance with bursts of sunshine, after a little mizzle this morning. Quite blue over Mount's Bay, with towering Cb just visible to the east.

I would have thought thunderstorms always present a danger to life?
