This is the moment people in the Cornish seaside town of Fowey knew the weather was about to turn - a funnel cloud appearing out to sea, just before the heavens opened and a deluge flooded the town.
Stunned onlookers spotted the cloud formation and feared it was a tornado coming in onto the south Cornish coast, as storm clouds rolled in when the heatwave broke in the far south west on Monday.
Soon the streets were ankle-deep with heavy rain as water poured off the dry hills and into the frequently-flooded coastal town.
