The South African Weather Service (Saws) has issued impact-based warnings for disruptive rain, damaging waves and snow in the Western and Northern Cape provinces over the weekend.
A Yellow Level 4 warning was issued for damaging waves from Friday until Saturday in areas including the City of Cape Town, Bitou, George, Hessequa, Knysna and Mossel Bay. A Yellow Level 4 warning was issued for disruptive rain over the same period.
“An intense cut off low pressure system is expected to affect the Western and Northern Cape from Friday evening into Sunday, resulting in thundershowers throughout the provinces. Rainfall accumulations are expected to be 30-40mm over the City of Cape Town district between Friday evening and Saturday, and 40-60mm over the Cape Winelands, Overberg and Garden Route districts from Saturday morning, persisting throughout the day.”
Saws warned that high rainfall could result in flooding.
A Yellow Level 4 warning was also issued for disruptive snow from Saturday until Sunday.
Saws said the intense cut off low pressure system was expected to result in snowfall over most of the high-lying areas of the Western and Northern Cape provinces.
“Snow accumulations are expected to be at most 5mm over the mountains of the Cape Winelands (Matroosberg and Koue Bokkeveld mountains) and Little Karoo (Swartberg mountains), but 5-12cm over the mountains of the southern high ground of Namakwa and Central Karoo mountain ranges between Saturday early morning and Sunday morning.”
