Metsul’s warning
A “storm surge with extreme precipitation” will advance towards Uruguay in the coming days and could lead to the formation of a cyclone, according to the Brazilian meteorological agency. Metsul.
According to the report, the system will originate as “a low pressure center” over northeastern Argentina and Paraguay, but its most relevant impact for Uruguay will come towards the end of the week.

Storms and strong winds
The passage of the system will bring with it a scenario of instability. In the run-up to its arrival, storms with severe characteristics are expected in the region, with “lightning, hail of various sizes and strong winds”within the framework of a process that will already be active from Argentina.

Although the most extreme accumulations will be concentrated in northeastern Argentina—where “200 millimeters or more, with risk of flooding”—, the phenomenon will have a regional impact and will fuel the instability that will reach Uruguay.
The persistence of the system, which will move slowly, will favor several days of bad weather in the Southern Cone, with frequent rains and thunderstorms that will move towards Uruguayan territory as the week progresses.
