After spotting this rainbow and stormy clouds approaching I set up and took several shots. On the first shot the rainbow appeared over land and the cliffs were clear and sharp. I watched it slowly move over the sea, taking several more shots. As I took this final shot the temperature dropped quite dramatically, and the wind picked up disturbing the quite calm sea. Then the thunder started, and the hail, followed by heavy rain....and I was running for shelter. I was awestruck on how quickly the storm came across the bay and the subsequent drop in temperature!
