The first significant snowfall for the year is expected over the Drakensberg on Friday.
Richard Le Sueur of Snow Report told TimesLIVE that between 10 and 25cm of snow has been predicted.
"We’ve been seeing snow on the horizon for a few weeks now. We’ve been watching the data for a few days and it has been up and down.
"Now it seems likely that high-level snow will fall over the Drakensberg.
"There may be a small chance that it may fall over other places," said Le Sueur.
Snow is expected to fall over the high peaks of the northern, central and southern Drakensberg.
"At this stage it’s looking like it's going to be anything from 10 to 25cm of snow."
Le Sueur said although there was a slight sprinkling of snow in January, Friday’s predicted snowfall would be the "first significant" snow for the year.
"We think we’re in for a pretty good winter," he said.
Le Sueur said no snow was predicted for lower levels.
