The ReliefWeb outlook says La Niña conditions are active and expected to last until early 2021, likely weak to moderate. East Africa faces a likely drier-than-average short rains season and possible dry Long Rains, while Southern Africa's maize prospects look favourable.
Drier East Africa and favourable Southern Africa conditions shift regional food security more than global feed grain prices, though a weak La Niña adds modest weather risk to Southern Hemisphere crops.
