The presence of unstable air combined with high sea temperatures led to a tornado forming of the coast between Alicante and Benidorm. That must have been a spectacular sight whilst it lasted.
The sun came back out and all was peace again. Not for long though because another supercell formed and dumped 14 litres per square metre of rain on Elche and 3 litres per square metre on Alicante. We could hear the thunder even though it was some distance away.
