While the northern parts have begun to feel the beginning
Gordon Richardson had the following to say in the forums section of the website.
“The synoptic outlook looks a bit different this morning (Mon 15th), with the deep low intensifying and a secondary front likely to brush the Western Cape on Wed 17th, bringing wet and windy weather. Very cold conditions are expected overnight into Thurs 18th.
This frontal boundary is clearly visible on the EUMETSAT airmass Antarctic sector, along with a strong jet-stream (shown in purple): oiswww.eumetsat.org/IPPS/html/MSG/RGB/AIRMASS/ANTARCTIC/
The SAWS aviation WAFC chart for 18Z shows a strong jet-stream (100kts) in a loop approaching CT, which brings cold air from the Antarctic: aviation.weathersa.co.za/aviationold/get…p?1=sigwaf18&2=2
By contrast the low approaching Cape Town today looks very weak, though it should make a direct hit and will bring some rain overnight.”
The South African Weather Service has also issued the following warnings.
