A tornado surprised local residents of a busy port resort following a spell of sea storms and atmospheric phenomena that swept over the country’s coastlines.

The twister appeared in Puerto Limon, the capital city and main hub of Limon province in Costa Rica.

The National Meteorological Institute (IMN) said that the phenomenon was caused by a cumulonimbus cloud, a towering vertical cloud formed from water vapour that is carried upwards by powerful air currents.

The sea storm hit the coast of Costa Rica at 9am on 22nd March.

IMN representative Rebeca Morera called the atmospheric disturbance a "waterspout", an intense columnar vortex found over a body of water that was "formed by a cumulonimbus cloud".

She added that waterspouts "are similar to tornadoes that form on the mainland" and suggested that the storms over the Caribbean at the moment make the phenomenon more likely.

"In tropical regions such as ours, sea storms are more common than tornadoes. Generally speaking, they are also more like to occur early in the morning."

Waterspouts have a five-part cycle starting with the formation of a dark spot on the water surface, then a spiral pattern. This is followed by the formation of a spray ring and then the funnel, before finally disappearing.

Morera confirmed that the twister did not cause any damage to the port city and lasted "several minutes" before fading away.

She added that these phenomena are common on both the Atlantic and Pacific coasts of the country.
