A drop in temperature on August 26 gave rise to a waterspout on Lake Zurich.

While the lake water remained at 23 degrees Celsius (73 Fahrenheit), air temperatures dipped to only 9 degrees, creating what local forecasters said was the perfect mix for a vortex.

Waterspouts also formed on Lake Zug and Lake Constance, local reports said.

The Local said temperatures were due to rise again during the week. Credit: @OKindhauser via Storyful
