Artigas, Uruguay – On February 19, 2026, X user Mati Mederos recorded striking footage while storm chasing in the rural interior of Artigas, Uruguay, along the border with Argentina, as a powerful severe thunderstorm rapidly intensified under an orange alert issued by INUMET for strong to severe storms.

The video begins with a sweeping view of open countryside—green fields, scattered trees, and distant hills beneath a sky turning increasingly dark—when a colossal, perfectly shaped roll cloud surges forward like a vast cylindrical wave spanning the horizon. Its underside appears dark and turbulent, marked by structured striations and subtle rotation, a clear gust-front signature from an organized multicell or supercell system.

As the handheld camera remains steady and pans slightly, the cloud’s sharp leading edge advances at low altitude in some areas. Strong surface winds whip through grass and bend trees, lifting dust and debris into swirling vortices ahead of the main rain core. Lightning flashes intermittently within the storm’s churning interior, while the entire system moves with striking speed and cohesion, transforming the afternoon sky into a dramatic scene.

The footage alternates between wide landscape shots and closer views of the cloud’s textured structure, emphasizing the immense scale and visual impact of the phenomenon as it dominates the terrain.

Authorities had placed Artigas and Salto under orange alert, reporting intense winds that overturned heavy trucks on the Argentine side of the border, followed by torrential rainfall. The video quickly became one of the most widely viewed recordings of the day’s severe weather outbreak in the region.
