In the evening of April 23, 2019, an arcus formed over Bordeaux (Gironde). Disturbingly, this impressive roll of clouds is well known to meteorologists.
On the evening of April 23rd, 2019, the sky of Bordeaux was covered with a cloud worthy of the most apocalyptic films.
No worries, it was not a remake of Roland Emmerich ‘s 2012 film, but an arcus, a phenomenon well known to meteorologists

Forecaster at the Chaîne Météo , Régis Crepet explained the phenomenon:
“This cloudy arc is formed with the arrival of cold air that condenses on contact with hot air. The arcus is a precursor of the storm, even if it is not systematic. “
“An atmosphere of the end of the world”
Generally, it defines the beginning of precipitation. “It creates an atmosphere of end of the world but it is very aesthetic to see,” added the meteorologist.
