The West, Midwest and South Plateau of Santa Catarina regions were affected by thunderstorms between last Friday (18) and Saturday (19), according to the State Civil Defense. The city of Anita Garibaldi was hit by heavy rain and hail.
Images that circulate on social networks show a street in the municipality covered by a bulky layer of ice. See below:
Also according to the Civil Defense, on Saturday morning, a storm reached part of the municipality of Chapecó, with winds between 80 to 90 km/h. The agency issued numerous alerts to the region where the city is located.
Although the storm has passed on the radar-which can mitigate the quality of the information generated-based on the characteristics observed before and after its passage, it is possible to say that the storm in part of the municipality is a downburst (atmospheric microexplosion).
Downbursrs are characterized by an intense descendant current (winds) that fall from the base of the storm towards the surface, spreading radially when it reaches the ground.
