In Argentina, another heavy rain event appears likely this weekend over La Pampa and southern Buenos Aires with moderate to heavy rain elsewhere in the region. Rain is highly unfavorable for mature crops and will likely delay and disrupt the corn and soybean harvests. Losses due excessive rain and local flooding appear likely due to this weather pattern.
In Brazil, favourable conditions for developing second crop corn in central Brazil. Favourable conditions for maturing and harvesting soybeans in southern Brazil at this time. Rainfall over RGDS during the next 5 to 7 days may favor late filling soybeans but would be unfavorable for maturing crops and harvesting.
