The KNMI issued a code yellow on Tuesday evening because of waterspouts in the Wadden area.

Several specimens had been sighted earlier that evening.

What is a waterspout?

A code yellow for waterspouts is not very special, explains Marsel Blok of Weerplaza.

"We actually see it happen once or more every autumn above the warm coastal waters, often after a waterspout has been spotted."

The fact that the KNMI issued a code yellow on Tuesday may have to do with previously observed waterspouts south of Terschelling.

A waterspout is not an everyday occurrence.

Waterspouts can be formed by the collision of cold air above with relatively warm water and often occur at the end of the summer or in the autumn.

Strong wind speeds can arise in the funnel-shaped trunk.

Such a waterspout often remains above water.

"Such drains are not entirely without danger," says Blok.

Small water vehicles such as sailing boats in particular can be damaged as a result.

Water sports enthusiasts should also pay attention.

When such a waterspout comes ashore, it can lift small objects.

This often does not take very long, because the waterspouts above land often lose their strength quickly, Blok says.

"They can't be compared at all to tornadoes, which are generally many times stronger and can really cause great damage."
