Weather Warning - SA Coastal & Interior + New Climate Records

Gale force southeasterlies (35kts or 65km/h) are expected in places between Cape Point and Plettenberg Bay. Heavy falls of rain and showers in places over the south-eastern part of Northern Cape, southern and central Free State and the eastern part of Eastern Cape. Hot and humid conditions which may lead to dangerously high levels of discomfort are expected over the northern coast of KwaZulu-Natal.

NVDL: The rain must blow now - in the Cape - and get it over with. I've heard reports that PE and Bloem are insufferably hot, and PE is having a lot of violent stormy weather.

New Climate Records Yesterday + Weather Warning

Disturbed weather patterns, essentially weather chaos, is what Climate Change is all about. Warming (leading to droughts and fires) is a trend, but so is freaky cold weather in midsummer, floods in a dry season, that sort of thing. Have a look at the climate records below. All are for one day, yesterday.

Alert: National Weather Warning

Heavy falls of rain, that may lead to flash flooding in some places, are expected in the Breede River Valley, Overberg and Eden Districts of the Western Cape and along the south coast of the Eastern Cape and southern KwaZulu-Natal.

These heavy falls are likely to persist into Thursday. Very cold, wet and windy conditions will set in in the interior of the Western Cape and the western high ground of the Northern Cape, persisting on Thursday. Very rough seas, with wave heights exceeding 5 metres, are expected to develop between Cape Columbine and Algoa Bay, persisting on Thursday. Thundershowers in the east of the Eastern Cape, on the Mpumalanga highveld and in northern KwaZulu-Natal may cause isolated heavy falls of rain that could lead to localised flooding.

KwaZulu and Gauteng Rainfall Records, Weather Warning And Weekend Weather


Rainfall records

Looking at the table of rainfall figures below one can see that a number of places received heavy rainfall, with Durban, Greytown and Pennington South breaking their previous 24-hour rainfall record for November. It is also interesting to note that on this one day Durban received 251% of its normal rainfall for the first ten days of the month, while Mount Edgecombe received 227% and Richards Bay 165%.

NVDL: Many of the previous records are recent, 4 out of 6 between 2000 and 2006. Climate change will affect SA by creating a vastly wetter Eastern Region, and drying the Western Interior. All areas will be more susceptible to storms, and extreme weather - floods and droughts.
Also yesterday:
Highest Daily Rain: Was - 49.4mm (2001-11-24) Now: 58.0 (2007-11-06) Witbank

Warning:
Isolated heavy falls of rain are possible in the escarpment and lowveld areas of Mpumalanga and Limpopo, including the Soutpansberg.
