A cold front has the potential to bring severe weather to central South America from Saturday night into Sunday night.
The front will move through Montevideo and Buenos Aires late Saturday night into Sunday, before moving through interior Uruguay and more of northern Argentina on Sunday afternoon and Sunday night.
The main threats from these storms will be damaging winds and torrential downpours, however hail and even isolated tornadoes cannot be ruled out for the region, especially on Sunday.
With such a slow-moving system and so much precipitation expected to fall, there is the risk of flooding for parts of the region. The front will be moving slow enough to bring some locations nearly 2 inches of rainfall, if not more.
Even mariners will take notice; the front is expected to bring strong winds to the Rio de la Plata, bringing rough seas and creating a problem for small crafts there.
During early next week, the front will eventually lose strength as it pushes north into southeastern Brazil and Paraguay. Less severe weather is expected there.
Following the front, cool conditions and some sunshine is expected to return. However, late week another storm system is expected to develop and will likely bring another round of showers and thunderstorms to the region, with the potential for more severe weather.
