The latest predictions charts have also changed since this morning. These charts now reflect the possibility of moderate to heavy rain in areas of the Western Cape, Northern Cape, Southern Cape and Eastern Cape.
Quite a significant change since this morning's charts.

I would however like to reiterate that the amount of rain in a specific area as a result of a cut-off low is difficult to predict. When an upper-level low-pressure system becomes "stuck" in one place due to a lack of steering currents, it is known as being "cut off". The usual pattern which leads to this is the jet stream retreating, leaving the then cut-off system behind.
What can we possibly expect in the next few days? (Please note weather is not an exact science. I prefer real time weather observations rather than to rely on prediction charts.) However here is my personal outlook for the above period.
1. Moderate to heavy rain.
2. Possibility of thunderstorms
3. Strong to gale force winds (23 - 65 km/h)
4. Flash Flooding
5. Rough Seas
6. Bad visibility
7. Flooding
It is still to early to say for certain if the system will result in severe weather, however at this stage it appears that this is a significant system that should be observed full time as from today and throughout the rest of the week.
MSBWX hereby ask the general public to forward any reports of severe weather conditions and flash flooding to the MSBWX. Use your cellphone, digital camera, email and private weather station etc. in gathering and forwarding information, photos and data to MSBWX. Email observations to MSBWX by clicking HERE.
