Snow Forecast : Western, Northern and Eastern Cape, Lesotho : 5-7 September 2018


Our snow forecast from Monday remains largely valid, but there have been a couple of changes. The cold front made landfall in the Western Cape yesterday, and we suspect that there is already light snow across most of the high peaks in the Cedarberg and the HexRiver Mountains this morning. Going forward for today, we ae expecting light snowfalls to continue over the high peaks of the Cedarberg and Hex River Mountains, with some slightly heavier falls possible further south on the mountains around Wellingon.

Tomorrow morning (Thursday), we are expecting to see some light snowfalls over the Swartberge north of Oudtshoorn, and maybe even a dusting on the Outeniquas, which is expected to continue through most of Thursday. By Thursday afternoon, we are expecting to see snowfalls return to the Cedarberg and Hex River Mountains, with light snow possible over all the high peaks and ranges between Wellington and Oudtshoorn. We also expect light snowfalls to start in the Northern Cape during Thursday. The area between Beaufort West in the Western Cape and Cradock in the Eastern Cape could also see snowfalls at this time, with some heavier falls on the extreme high ground.

Through Thursday night and into Friday morning as the front moves east, we should see snow impacting further into the Eastern Cape from Graaff-Reinet through to Somerset East and then to Hogsback, and possibly extending even further east into the Eastern Cape Drakensberg regions and Lesotho.

During Friday, we are seeing quite a few isolated snowfalls across a few regions, namely, the south western parts of the Eastern Cape, the northern reaches of the Cedarberg in the Western Cape, the Sutherland area in the Northern Cape and most high peaks between Worcester and Uniondale in the Western Cape.

As we look at the data for Saturday, there is still a fair amount of volatility in the data, but we are currently seeing potentially heavier falls in the southern high ground of the Northern Cape, with some heavier falls also possible in the Eastern Cape areas like Steynsberg, Molteno and Nieu-Bethesda during the morning. As Saturday progresses, snowfalls seem possible still in the Eastern Cape areas. By Saturday evening, snowfalls will start tailing off in the central areas of the Eastern Cape and move further east into the Eastern Cape Drakensberg again.

During Saturday night and into Sunday morning as the front moves further east, we are seeing possibilities of the snow falls intensifying over the Eastern Cape Drakensberg, into Lesotho and light snowfalls moving into KZN on the KZN Drakensberg, with some possible lower light snowfalls for Kokstad, Matatielle and Underberg areas. By sunrise on Sunday, we are seeing some good snowfalls over the entire KZN Drakensberg, the eastern parts of the Maluti Mountains in the north of Lesotho and over eastern Lesotho. At the moment, we are not expecting the snow to continue past sunrise on Sunday as the front heads east and moves out to sea.

At this stage, we would regard to predictions for Saturday and Sunday as ‘advanced’, and as such, they could easily change over the course of the next few days. This system has been incredibly difficult to forecast, as we have been seeing high levels of volatility in the model runs since we fist spotted this system over a week ago. We will keep you updated over the next few days as we see changes in the weather data, as well as bringing you all the snow news as it happens. Please remember to send us your photos, video and reports if you see snow. Keep warm, and be safe out there.
