These are the images expected to end the drought. First, the mammatus clouds are claimed in the sky, which will prepare the rain, which ends up arriving, as seen in this sequence of photographs taken from Sant Pere de Torelló, in Osona.

These formations were first described in 1894 by William Clement Ley, who was a pioneer clergyman in meteorology who used weather forecasts.

Specifically, the images of Las Fotos de los Lectores de La Vanguardia are captured from the viewpoint of the sanctuary of Bellmunt, in Osona, on the border with the counties of Ripollès and Garrotxa.

The sanctuary is located at the top of the Sierra de Bellmunt, at an altitude of 1,246 metres. This location is an excellent observation point, as can be seen in the photographs.

The mammoth cloud brings hope of rain at a time of drought in Catalonia. Although its color is normally bluish-grey, it can also have a reddish coloration, turning golden.

Mammatus clouds can persist in the sky from a few minutes to several hours, until they fade and disappear. It is very common for mammatus-producing storms to generate strong updrafts and thunderstorms. That is why air navigators avoid going through storms with mammatus.
