Severe weather alert: Cold, wet and windy conditions are expected to affect large parts of South Africa during the upcoming long weekend, with the South African Weather Service (SAWS) warning of freezing temperatures, widespread rainfall, damaging winds, rough seas, and snowfall across several provinces.

The weather system is expected to make landfall over the Western Cape and Northern Cape on Sunday, 9 August, before moving eastward and intensifying over the country’s interior on Monday. Forecasters have urged South Africans to prepare for hazardous weather conditions that could disrupt travel, damage infrastructure, and increase the risk of flooding in vulnerable communities.

The latest Severe weather alert: Cold, wet and windy conditions warning comes as millions of South Africans prepare to travel during the long weekend, prompting authorities to encourage motorists, residents, and businesses to remain alert.

Severe weather alert South Africa: Powerful cold front approaching

The South African Weather Service (SAWS) has issued an early warning for a significant cold front combined with an upper-air trough expected to spread across much of South Africa.

Meteorologists say the weather system will first affect the Western Cape and Northern Cape before expanding into the Eastern Cape and eventually moving into the central and eastern provinces.

SAWS expects:

• Cold to very cold temperatures
• Heavy rain and widespread showers
• Strong to damaging winds
• Rough sea conditions
• Snow over mountain ranges
• Localised flooding
• Dangerous driving conditions

Officials say weather conditions are likely to worsen as the upper-air trough strengthens while moving inland.

South African Weather Service (SAWS) warns of widespread impacts

According to the South African Weather Service (SAWS), the approaching system is capable of producing dangerous weather over several days.

The weather service warned that residents in affected areas should prepare for:

• Flooding of low-lying roads and bridges
• Flooding in informal settlements
• Reduced visibility during heavy rain
• Fallen trees caused by strong winds
• Damage to roofs and infrastructure
• Possible electricity outages
• Hazardous coastal conditions for small vessels

Authorities are urging local municipalities and disaster management teams to remain on standby should emergency interventions become necessary.

Cold front South Africa expected to spread east

The cold front will initially impact:

• Western Cape
• Northern Cape

It will then move into:

• Eastern Cape
• Free State
• KwaZulu-Natal
• Mpumalanga

As the system advances, temperatures are expected to drop sharply across inland regions.

Weather experts say residents should prepare for several days of uncomfortable and potentially dangerous weather, especially in higher-lying areas.

Snow and heavy rain forecast for multiple provinces

One of the biggest concerns surrounding the latest snow and heavy rain forecast is the expected snowfall over several mountain ranges.

SAWS says the highest confidence for snowfall currently exists in:

Western Cape mountain ranges

Higher peaks are expected to receive snowfall together with freezing temperatures and strong winds.

Northern Cape mountains

Snow is also forecast over elevated parts of the province as the cold front arrives.

Free State mountains

As the upper-air trough deepens, snow is expected over mountainous areas of the province.

KwaZulu-Natal

Mountain regions bordering Lesotho may experience snowfall together with freezing temperatures.

Mpumalanga

High-altitude areas could also receive snow as the weather system shifts eastward.

Forecasters say there remains a smaller possibility of light snowfall over other elevated regions, although confidence is currently highest in the mountain ranges mentioned above.

Long weekend weather warning for motorists

The latest long weekend weather warning comes as thousands of South Africans prepare to travel.

Motorists are being advised to exercise extreme caution because of:

• Wet and slippery roads
• Reduced visibility
• Flooded crossings
• Strong crosswinds
• Falling trees and branches
• Possible snow-covered mountain passes

Transport authorities may also issue road closures should conditions deteriorate significantly in high-risk areas.

Drivers are encouraged to:

• Reduce speed
• Increase following distance
• Avoid flooded roads
• Monitor weather updates
• Delay non-essential travel where necessary

Flooding risk remains a major concern

Persistent rainfall could lead to flooding across several provinces.

SAWS warned that localised flooding may affect:

• Low-lying communities
• Informal settlements
• Roads
• Bridges
• River crossings

Communities located near rivers and streams are encouraged to remain vigilant as water levels could rise rapidly following prolonged rainfall.

Emergency services may also monitor areas previously affected by flooding during earlier winter storms.

Damaging winds may cause infrastructure damage

In addition to heavy rainfall, strong winds are expected to accompany the weather system.

According to SAWS, damaging winds could result in:

• Fallen trees
• Roof damage
• Damage to power infrastructure
• Electricity interruptions
• Dangerous driving conditions
• Coastal hazards

Residents are advised to secure outdoor furniture, loose roofing materials, and other objects that could become airborne during strong gusts.

Coastal conditions expected to become dangerous

The approaching cold front will also affect South Africa’s coastline.

Strong winds and rough seas are expected along parts of the Western Cape and Eastern Cape coastlines.

Small fishing vessels and recreational boats are advised to remain in harbour until conditions improve.

Beachgoers should also exercise caution as rough waves and strong currents may create dangerous swimming conditions.

Disaster management teams remain on alert

Local disaster management authorities are expected to monitor the developing weather system closely.

Municipal emergency services may activate response plans should flooding, snow, or wind damage become widespread.

Residents are encouraged to:

• Follow official SAWS weather updates
• Listen to local emergency announcements
• Prepare emergency supplies
• Charge mobile devices
• Keep flashlights available in case of power outages

Preparedness remains one of the most effective ways to reduce risks associated with severe weather events.
