    More Flooding Rain for Argentina and Uruguay

    A week after torrential rainfall flooded portions of northern Argentina and Uruguay, another potent storm is set to unleash a second round of downpours on the region this weekend.

    Warm, moist air streaming southward from Brazil will interact with a strengthening storm system Saturday, spreading heavy rain from Cordoba to Buenos Aires, Argentina.

    A large swath of potentially flooding rainfall is then expected to spread through northeastern Argentina and into Uruguay and southeastern Brazil Sunday.

    Cities that may have to deal with life-threatening flooding include Resistencia and Santa Fe in Argentina, Paysandu and Montevideo in Uruguay and Rio Grande in Brazil.

    As much as 200 mm (8 inches) of rain can fall in some spots with a large area of 50-100 mm (2-4 inches) as the storm system tracks toward the southern Atlantic Ocean by Monday.


    AccuWeather.com Senior Meteorologist Jason Nicholls noted, "the ground is already saturated from last week and more rainfall will exacerbate flooding issues. Two rounds of heavy rainfall, while not unheard of, is unusual for this time of the year in northern Argentina."

    The combination of a vigorous atmospheric disturbance and air with rich moisture will also promote a threat of severe thunderstorms. While flooding is the main concern, a few heavier thunderstorms could contain wind gusts in excess of 50 mph (80 km/hour) as well as hail and perhaps a tornado or two.

    The stormiest weather is expected from Sunday into Monday; however, a prolonged dry stretch of weather is expected to begin by the middle of next week.

    This will be the second round of stormy weather in the last week for the region. The month of November began with a similar storm bringing 75-150 mm (3-6 inches) of flooding rain.

    Resistencia and Cordoba, Argentina, were both swamped by 134 mm (5.27 inches) of rain. Buenos Aires was spared the brunt of the deluges, receiving 48 mm (1.89 inches).

    The round of downpours that drenched the area to start the month brought relief from short-term drought and was good news for many agricultural interests.

    This batch of rain will prevent farmers from being in the fields for several days. However, the enhanced soil moisture as a result of the rain should be a positive for crop production.
