Forecasters expect South America's rainfall pattern to shift in November, with drier, warmer conditions in southern Brazil and Argentina and more rain in central Brazil. La Niña's growing presence in the Pacific is cited as the main driver.
Dryness in Argentina and southern Brazil threatens wheat and early corn and could tighten supply, supporting grain and meal prices, while rain in central Brazil helps soybean germination.
