What is shelf cloud
It is a huge cloud whose edges give the impression that they are approaching the ground. In more detail, according to the US National Weather Service, a shelf cloud is a wedge-shaped cloud that forms at low altitude during a storm and is accompanied by heavy rainfall and strong winds.
In fact, the strong wind usually precedes and follows the outbreak of the storm.
These clouds are caused by the sudden movements of warm and cold air masses. They look impressive, maybe even scary and many mistake them for a tornado as they appear relatively quickly on the horizon. But in reality, shelf clouds are harmless but highly impressive.
The clip was taken by a local resident on Saturday morning and posted on Instagram and other social media platforms. The timelapse video shows clouds moving over the buildings. They appeared due to the weather in the Brazilian city, in which there were storms, lightning and strong winds, according to a report by G1.
