The South African Weather Service (SAWS) has warned of a powerful cut-off low pressure system expected to bring widespread cold, wet and disruptive weather conditions across parts of the Western Cape and Eastern Cape from Wednesday, June 3, into Thursday, June 4, 2026.
SAWS said the system, combined with a ridging surface high-pressure system, will “markedly affect the central and western interior of South Africa,” with the most severe impacts expected over the Cape provinces and adjacent interior regions.
The weather service cautioned that the system will generate widespread rainfall, strong winds, and a sharp drop in temperatures, with conditions posing risks to life, infrastructure, and transport networks.
SAWS warned that rainfall linked to the system is expected to become widespread midweek, particularly across the Garden Route District and parts of the Eastern Cape.
“The anticipated rainfall may lead to localised to significant flooding of susceptible areas, including roads, bridges, low-lying settlements, and river crossings,” the statement read.
It further warned that “fast-flowing streams and rivers may pose a danger to life,” while major transport routes could be affected by flooding and poor visibility.
Authorities have urged motorists and residents in affected areas to avoid unnecessary travel during peak rainfall periods and to never attempt to cross flooded roads or bridges.
SAWS also flagged the possibility of light snowfall over elevated terrain in parts of the Cape provinces due to significantly dropping freezing levels.
The service said snowfall could occur over:
- The interior of the Eastern Cape
- Southern parts of the Northern Cape
- North-eastern high ground of the Western Cape
While the forecasted accumulation remains light, SAWS cautioned that “travellers and communities in mountainous areas are nevertheless advised to remain informed of forecast updates,” as conditions could change.
Alongside rainfall and cold conditions, SAWS warned of strong winds and rough sea conditions along the south-western and southern coastline of the Western Cape.
These conditions may make navigation hazardous, particularly for small vessels and recreational watercraft.
SAWS has issued an Orange Level 5 warning for disruptive rainfall, indicating a high risk of severe impacts.
“Disruptive rainfall resulting in danger to life, flooding of roads and bridges, rapidly flowing streams and rivers, and possible closure of major roads is expected,” the service said, adding that this applies to the eastern parts of the Garden Route District and areas stretching between Plettenberg Bay and East London.
A Yellow Level 2 warning has also been issued for additional areas, where “localised flooding of settlements, roads, low-lying areas, and bridges is expected.”
SAWS has called on the public and authorities to remain on high alert and take precautionary measures ahead of the system’s arrival.
Residents are advised to monitor official updates, secure outdoor property, and ensure emergency supplies are available.
The weather service also urged communities to “provide adequate shelter, warmth and protection for livestock and pets,” and to avoid all unnecessary coastal and marine activities during the warning period.
