Capri, Italy sees a rare natural phenomenon, a double waterspout

In Italy a double waterspout was seen stretching across Capri's iconic Faraglioni rock formations Saturday in a rare natural phenomenon.

The two swirling spouts emerged from heavy clouds that were hovering over the island.

Winds blowing from opposite directions collide to create localised areas of spinning air, atop the water's surface.

Waterspouts are common in later summer months and autumn over the Mediterranean, when cool air moves over relatively warm water.

Capri continues to be one of Italy's most popular tourist destinations with an estimated three million people visiting the island every year.
