As of 5th September 2025, South Sudan continues to face severe flooding, affecting over 1.4 million people and exacerbating public health risks, particularly the cholera outbreak (UNOCHA). The floods have destroyed vital infrastructure, including roads, bridges, and other communication networks. This in some areas has isolated flood affected populations, making it difficult for humanitarian agencies to access the affected communities.
An estimated 273,000 people are affected in 12 counties across four states, with Jonglei and Unity States accounting for over 91 per cent of those impacted.
Escalating violence and conflict in South Sudan since February 2025 have triggered renewed displacement and growing humanitarian needs across the region (UNHCR), following a sharp escalation of violence and insecurity since February 2025 (UNHCR).
Flood water has submerged farmland, homes, humanitarian compounds a disrupted access to education, health, nutrition and water services (UNOCHA).
