My power was only restored now. Two dudes rocked up in a bakkie, opened the CB box two houses down, flipped two switches and voila. Took them all of 3 minutes to fix the fault.

The fsking breaker box wasn't even locked. Could have flipped the bloody switches myself 36 hours ago.

Not sure what data they are looking at but I just had a look at the historical data and we've hit 100mm over 24 hours a few times already.

I also find it a bit hard to believe, that is why I called our resident expert..

Unfortunately the SAWS only shows the data for the latest 24 hours, and Mon 25th was a public holiday, so I couldn't see anything on their website for Sun 24th. Cape Town W/O is at the airport, which has only been around since the 1950s(?). There are older stations such as SAAO in Observatory dating to the 1820s.

I don't think it's possible to give 1:100 year ratings for a particular weather station. The event as a whole was not truly exceptional, see the Laingsburg floods for example. Measuring is hard, and historical records over long periods are sporadic (both in time and by location). The effects of rainfall are greatly exaggerated by mountainous terrain (specifically the area in the Overberg). The highest point source was SAEON Dwarsberg with 375mm in 36 hours, which is pretty exceptional.

Read what the experts say. Short answer, it's complicated:

Why more than two months worth of rain fell in Western Cape weekend storm

Daily Maverick spoke to experts who explained what happened and why it may happen again.

Normally, frontal systems will pass us and then they’ll move quite quickly towards the east. And this little system is cut off from that flow and so it stays semi-stationary. So it hangs around and it’s very unpredictable. It doesn’t move as quickly as a frontal system and therefore if it decides to start raining in a place, it can keep raining there for two or three days,” he explained.

Turner from the weather service confirmed this, saying that in just two days the Cape Winelands and Stellenbosch received more than 193mm of rain. The City of Cape Town had 143mm of rainfall over the same period.

Daily Maverick reported in June that Dr Piotr Wolski, the chief research officer for hydroclimatology at CSAG, said, “If we look at total rainfall between January and now … at some locations, this year’s values are the highest on the recent record (we are looking at 20-40 years of data here)”.

Daily Maverick has reported that Western Cape local government, environmental affairs and development planning MEC, Anton Bredell, said the province is characterised by a highly variable weather and climate system. This means it has always, and will in future, experience all manner of extreme weather and climatic events including flooding, drought and extreme temperature.

Studies have found that at least 334 major flood events occurred in the Western Cape between 1900 and 2018, with roughly three events occurring in any given year. However, this varies — in 2008, the province experienced 20 floods, and 15 in 1981, he noted.

huh ?

did you quote the wrong post ?

yes, I know its over 100mm. I'm just commenting on how far the records go back.
 
Is there anyone in Betty's or Pringle Bay willing to help some stranded tourists? They are stuck on Kleinmond side but their belongings are in Betty's. They have to fly back to Ireland on Sunday.
Maybe give them a lift from Palmiet bridge to fetch their stuff?
