September 2025 Heavy Rain – Weekend Weather Alert Issued Across South African Provinces

In choosing spring in South Africa, Filipinos will surely take the weather into account. On the 12th of September, 2025, the South African Weather Service (SAWS) had issued a severe weather alert warning of heavy rains, gale-force winds, and plummeting cold conditions affecting a number of provinces over the weekend. A further disturbance will mar daytime and recreation from Friday evening through Sunday following the passage of a cold front from the South Atlantic. Some areas might receive more than 100mm of rain, for which people are asked to make preparations against flooding and related hazards. Hence, the article will delve into the above alert more explaining its impacts and how to stay safe.

The Alert and the Affected Provinces

This South African Weather Service alert warned that a strong cold front would move through the country accompanied by heavy thunderstorms, winds reaching up to 90 km/hr, and sudden drops in temperature by 8-12 °C. The system would gain strength on the evening of Friday, 12th September; it should be at its strongest on the 13th of September, Saturday; and, thereafter, it should start weakening by Sunday afternoon. The coastal and mountain areas are seriously threatened by accumulated precipitation exceeding 50 mm in 24 hours over some vulnerable spots.

Hazards and Risks

This downpour could consider numerous hazards; however, floods descend into flooding in the low-lying areas and the city, whereas thin drainage grids could overcrowd said drain, blocking access to the roads. Cases show that upon flooding, especially from Cold Front events in 2023, more than 200 houses in Hermanus were flooded in six hours by 70mm of rain. If sufficiently strong, they uproot trees and power lines and collapse buildings, causing power outages and blocking transportation.

Preparation and Safety Tips 

One should lay the foundation for efficient safety and mitigations. The best option is to stockpile for at least 72 days: canned or dried foods, water, medicine, and a torch. Tie down or bring under shelter any garden furniture-that which could be prohibited during strong winds. Also, during the worst part of the storm, avoid any homely travels or driving.
