Hurricane Melissa, one of the most powerful storms ever recorded in the Atlantic, hit southwestern Jamaica on 28 October as a Category 5 system—the worst hurricane to hit the area since 1988—before crossing into eastern Cuba as a Category 3 the following day.
As of 30 October, an estimated 1,024,500 people have been affected by flooding across 29 counties in six states. Jonglei and Unity states account for nearly 87 per cent of those impacted.
During the night of 16–17 September 2025, heavy rains fell across most communes of the Nord-Ouest department, causing the Trois-Rivières River in Port-de-Paix to overflow suddenly. The floods resulted in extensive inundations across several neighborhoods in Port-de-Paix and Bassin-Bleu.
August has brought much wetter conditions across the country, improving crop and pasture conditions but also increasing flood risk and leading to expansion of flood areas.
South Sudan faces an escalating food crisis, driven by ongoing conflict, frequent climate shocks and economic instability. These overlapping challenges have deepened food insecurity across the country, putting millions at risk and straining already limited resources.
UNOCHA reports that over 9.3 million children are expected to suffer from high levels of acute malnutrition between June 2024 and May 2025 in Burundi, Eritrea, Ethiopia, Kenya, Rwanda, Somalia, South Sudan, Sudan and Uganda.
