    A strong storm system through Wednesday will bring not only heavy, flooding rain, but also the threat for severe weather through southern Brazil.

    The system responsible for the dangerous flooding and storms developed over northern Argentina Monday night and Tuesday bringing heavy rainfall across the largely agricultural region. The town of Presidencia Roque Saenz Pena in northeastern Argentina has seen about 5.5 inches of rain since late Monday. The heaviest rain will be moving away from Presidencia Roque Saenz Pena Tuesday night allowing the region to dry out.

    The heaviest rainfall through Tuesday night will be found from far northeastern Argentina into southern Paraguay, northern Uruguay and southeast Brazil.

    By Wednesday the heaviest rainfall will have wound down, but local downpours will still occur over southeast Brazil.

    Rainfall totals of 50-100 mm (2-4 inches) will be common across the region with local amounts up to 200 mm (8 inches).

    Though heavy rainfall is only part of the concern, there is also a positive side to this system as most agriculture over the region will see beneficial rain. Although the past few weeks have been somewhat wetter than normal, there has been little rain in the past year, making the drought an issue for many farmers.

    Some thunderstorms the past few weeks over the area have been spotty with heavy rainfall, but Cordoba, Argentina, saw over 230 mm (9 inches) of rain since Oct. 1st. The majority of that rain has fallen in the past 20 days.

    The threat for severe storms will be Tuesday afternoon into Tuesday evening across extreme northern Argentina, Paraguay, Bolivia and southern Brazil. The major cities in the threat of these storms include: Asuncion, Paraguay; Sao Paulo, Brazil; and Santa Cruz, Bolivia.


    The biggest threat from any severe thunderstorms will be torrential rainfall, but wind gusts of over 100 kph (60 mph) will be possible along with some hail.

    Severe weather is common across this part of South America during this time of the year as winter gives way to the warmth of spring.
