Lenticular clouds are a phenomenon that creates a look similar to a tornado. It occurs from time to time, particularly over volcanos. It has been observed at other times at Arenal and Irazu. An expert from the Volcanological and Seismological Observatory confirmed the current occurrence.
The strange cloud formations were photographed and the pictures have overtaken social media. Lenticular clouds form in conditions of high winds. They are unique to high mountainous areas, according to the National Meteorological Institute. They are different than clouds traveling fast with surface winds because they appear tornado-like.
