Waterspout observed off Praia da Rocha

A waterspout was observed off the coast of Praia da Rocha, Portimão, on April 21.

The phenomenon, which caused no damage, is equivalent to a tornado but happens at sea.

A spokesman from the Portuguese Institute of Meteorology (IM) said: “Weather instability last week was favourable to the formation of supercells, which is a thunderstorm that is characterised by the presence of a mesocyclone, a deep, continuously-rotating updraft. This may be the cause of this kind of phenomenon.”

A supercell can generate a column of air of great intensity, with ascending and descending movements, and winds can reach over 130kph.
