Waterspouts were spotted in Switzerland on Sunday and in Greece on Monday, eyewitness videos show.
Daniel Gerstgrasser, who lives near Lake Zurich, captured the natural phenomenon in Richterswil at 7:20 a.m. local time on Sunday.
Nicole Kenny was on holiday with her boyfriend when she saw the waterspout off the coast of Corfu on Monday. She said they were on a hydrofoil boat from Corfu port to Gaios on the Greek island of Paxos when she spotted the phenomenon.
“It’s definitely not what you expect to see on the first day of your holiday in Greece,” she told Reuters.
Waterspouts are tornadoes that occur over a body of water but never reach land. They are characterized by a funnel-shaped cloud.
Despite their ominous appearance, waterspouts are often much weaker than their land counterparts. However, they can pose a danger to any planes or boats that travel through them.
