Western Cape faces disruptive rain, wind and rough seas
A cut-off low is bringing cold, wet and windy conditions to the Western and Northern Cape, with official warnings covering disruptive rain, damaging winds and hazardous seas through Friday.
The South African Weather Service (SAWS) has issued a Yellow Level 4 warning for disruptive rain in parts of the Western Cape for Thursday, 3 September. The greatest concern is in the Overberg and Garden Route, where heavy rain may flood roads, low-lying settlements and other vulnerable areas.
Western Cape severe weather risks
Rainfall totals of about 15–25mm are expected across affected areas, with 30–45mm possible in parts of the Overberg and Garden Route. Pooling water could lengthen journeys, disrupt traffic and make gravel roads and low-water crossings dangerous.
A separate Yellow Level 4 warning for damaging winds and waves applies across parts of the Western and Northern Cape from Thursday into Friday. Strong winds are expected over the Namakwa district, Central Karoo, Little Karoo and sections of the Cape Winelands. Temporary structures may be damaged and flying debris could cause injuries.
Rough seas between Alexander Bay and Plettenberg Bay may disrupt small harbours and port operations and create hazardous conditions for vessels. People should remain clear of exposed coastal areas and avoid unnecessary activity at sea.
Cold conditions and Friday outlook
Very cold conditions are possible over higher ground, with daytime temperatures remaining below 10°C in places. Snow is possible on Friday morning over high-lying parts of the Eastern Cape Drakensberg and Lesotho, which may reduce visibility and affect mountain-pass travel.
SAWS has also flagged the possibility of severe thunderstorms developing over Gauteng, the Free State and North West from Friday afternoon. Their precise position and intensity remain uncertain, and residents should monitor later SAWS updates before treating this as a local warning.
Safety advice
Motorists should not cross flooded roads, bridges or low-water crossings. Residents should stay away from swollen streams and stormwater channels, secure loose outdoor items and follow instructions from municipal disaster-management officials. Anyone travelling through mountain passes should allow extra time and be prepared for rapidly deteriorating visibility and road conditions.
