Massive Shelf Cloud Precedes Intense Storm

Occurred on December 29, 2023 / Tres Passos, Rio Grande do Sul, Brazil

: "I am a civil engineer at Hospital de Caridade de Tres Passos. Around 7:30 AM on 12/29/2023, while I was working, I noticed a formation of clouds in the sky. I went up to one of the highest points to observe it because it was something I had never seen before. I started filming clouds arriving in the city, but I couldn't spend much time because a storm was coming. The storm caused a lot of damage to the municipality, such as breaking cables, blowing roofs off houses, and toppling trees. The entire city was left without electricity and mobile networks for around 12 hours. Some parts of the region remained in this situation for more than 24 hours. As the hospital had a generator, it was possible to share the video on my private profile."
