The South African Weather Service (SAWS) has placed parts of the Western Cape under a Yellow Level 4 warning today, as a potent weather system brings severe thunderstorms, heavy rainfall, and the risk of significant flooding to the region.
The alert, which is valid from midnight Sunday through midnight tonight, specifically targets the Overberg District and the Cape Winelands. Residents are urged to exercise extreme caution as the storm system moves through.
What to Expect: Rainfall and Hail Totals
Meteorologists are predicting a high-impact weather event characterized by intense localized downpours.
-
Rainfall Accumulations: Most affected areas can expect between 40mm and 70mm of rain.
-
Flash Flood Risk: In parts of the Overberg, rainfall could exceed 100mm, significantly increasing the danger of flash floods in low-lying areas and informal settlements.
-
Hail and Wind: The warning includes the potential for large amounts of small hail and damaging winds, which could impact property and agricultural crops.
Impact on Infrastructure and Travel
The combination of heavy rain and hail is expected to cause “major travel disruptions” across the province’s key transport arteries.
-
Road Hazards: Flooding of bridges and low-lying roads is likely. SAWS has specifically warned against attempting to cross fast-flowing streams or flooded causeways.
-
Obstructions: Falling trees and debris may block major routes, including sections of the N2 and R62 highways.
-
Service Disruptions: Localized power outages and disruptions to essential services are possible due to lightning strikes and wind damage.
National Weather Context: Disaster in the Eastern Cape
The Western Cape alert follows a weekend of devastating weather in the Eastern Cape. A massive hailstorm in the village of KwaNikhwe (Mbizana) reportedly destroyed homes and vehicles, leaving families homeless after golf-ball-sized hail tore through corrugated iron roofs.
Meanwhile, in the OR Tambo District, local authorities have confirmed that at least two people lost their lives over the weekend due to flooding and lightning-related incidents.
Safety Checklist for Residents
If you are in the warning zone (Cape Winelands, Overberg, or Southern Cape), follow these safety protocols:
-
Avoid Travel: If possible, stay off the roads during peak storm activity to avoid poor visibility and hydroplaning.
-
Clear Drainage: Ensure gutters and downpipes are clear of debris to prevent home flooding.
-
Unplug Electronics: Protect appliances from power surges caused by intense lightning.
-
Stay Informed: Monitor real-time updates from the SAWS Twitter/X handle or local radio stations.
