Anticipated scope and scale

Floods during the rainy season from June until at least October will affect about 200,000 people, mostly in southern Sudan. Particularly vulnerable are the displaced in southern Sudan, where there are 2.3 million IDPs and about 400,000 South Sudanese, 110,000 of whom arrived in 2017. Floods will damage key WASH infrastructure and increase the caseload of diseases including cholera and malaria. Houses will be destroyed and flooding will damage crops and isolate some localities, driving up food prices.

Aggravating factors: Existing outbreaks of malaria and cholera among refugee and IDP populations, poor WASH infrastructure, and overcrowded camps aggravate health conditions while the lean season worsens food security and nutrition levels.

Preparedness and response: Response will be limited as there is a lack of presence to respond to isolated flooding. Many South Sudanese refugees who arrived in 2017 are located in areas where there is limited or no humanitarian presence.

Priorities

WASH infrastructure will be damaged and safe water sources will be contaminated

Health response to outbreaks, including cholera and malaria

Shelter to repair and replace housing, especially in camps

Humanitarian constraints

Humanitarian access will be limited as roads are damaged and river transport is difficult. Some areas are likely to be cut off. As humanitarian presence is limited in some likely floodaffected locations, particularly West Kordofan and East Darfur, immediate response will be difficult. Poor reporting on weather conditions and diseases further constrains response.

Limitations

Existing WASH, nutrition, health, and shelter needs for the displaced and resident population is lacking. The number of IDPs is not accurate due to lack of access. Reporting on previous flooding is inconsistent.
