Date: 30th July 2025
The National Disaster Management Agency (NDMA) wishes to inform the public of a forecast of heavy rainfall over the next three days (July 30–August 2, 2025) as issued by the African Union’s Climate Centre (ACMAD/OCHA), which aligns with projections from the Sierra Leone Meteorological Agency (SLMet).
According to the forecast, Sierra Leone, along with other West African countries, is expected to experience deep convective cloud activity resulting in heavy cumulative rainfall ranging between 100mm to 150mm over the 5-day period. This level of precipitation significantly increases the risk of flash floods, landslides, infrastructure damage, and other related hazards, particularly in urban areas with poor drainage systems and communities located in flood-prone zones.
Low-lying coastal communities, hillside settlements, erosion-prone slopes, communities with poor waste management or blocked waterways, and areas recently saturated by previous rainfall are likely to be affected.
In light of the potential risks associated with the upcoming rainfall, the NDMA urges the general public to take the following preventive and safety measures:
☑ Relocate from high-risk locations. If you live in a floodplain, near riverbanks, or on unstable slopes, consider temporary relocation during the rainfall window.
☑ Households and communities should clear their gutters and waterways to ease water flow and reduce localised flooding.
☑ Report emergencies by calling NDMA’s toll-free line 1199, available on all networks.
This forecast serves as an early warning. NDMA remains in close coordination with the Sierra Leone Meteorological Agency and the African Union and will be monitoring the situation and responding swiftly to any emerging incidents.
The NDMA hereby encourages members of the public to stay vigilant and prioritise safety during this critical rainfall period.
