In a recent article in Nature, Chris Funk warned of unusually dry conditions in East Africa during the following months. The reason is the ongoing La Niña episode.

Our main partner in Africa, ICPAC, warned of unusually dry conditions from October to December already in August this year, and they issued an alert in October where they warned of the impacts on food security.
