Western Cape Heavy Rainfall – The Western Cape is currently bracing for one of its most intense weather events in recent history, as the South African Weather Service (SAWS) has issued a high-level flood alert due to severe rainfall between June 26 and June 28, 2025. The heavy downpour is expected to impact most parts of the province, with the most dangerous flooding forecasted in low-lying areas such as parts of Cape Town, George, and surrounding districts. The provincial disaster management teams have already activated emergency protocols and are coordinating evacuations for at-risk communities. Residents in flood-prone zones have been urged to leave immediately, while shelters are being prepared to accommodate displaced families. As of June 26, thousands have already been relocated as rivers rise and roads become inaccessible. Authorities have stated that the rainfall levels are expected to exceed 80mm in some areas within a 24-hour period, raising fears of flash floods, mudslides, and widespread infrastructural damage. Key services including transport, power supply, and water sanitation could be severely disrupted. The storm system, originating from the southwest Atlantic, is bringing not just rain but also strong winds exceeding 60 km/h in certain coastal towns. As the emergency response continues, residents are advised to stay informed via official channels, avoid unnecessary travel, and keep emergency kits ready. The below sections provide complete details on rainfall intensity, affected zones, precautionary measures, emergency contact numbers, and more.
