Raining quite hard in Southern suburbs - Constantia, Newlands, Rondebosch.

Just peeked out the window though, seems to have stopped for the moment.
 
i just want like 1 big ass cloud per dam. just go there and piss all over the dam. we don't need it here. just go already...

It's drizzling in Stellenbosch. So hopefully you were correct with the above.

No that is just a passing weather front. Will not result in much run off unless it lingers a bit in the catchment areas. But certainly very welcome locally
 
Any drop which has a diameter of 0.5 mm or less, is generally considered to be drizzle while larger than that is considered to be rain.

So please measure the drops before saying it's raining.

1mm of rain per square meter equates to 500 000 000 litres falling on this area https://en.wikipedia.org/wiki/Theewaterskloof_Dam. Drizzle or rain, we need a few mm!

Evaporation rates in summer can range as high as 10-15mm per day, under hot and windy conditions. A few mm of rain only slows down the evaporation rate, it doesn't increase the level in any measurable way.

A milimeter of rain on hot tarmac will not even wet the ground. It will wet your car windscreen though...
 
Some drops of rain forecast for Friday, seems like 5 to 10mm over the Peninsula. Enough to help fill the rainwater tank. But the last few months have seen many of these predictions peter out into nothing.

Although not a significant rainfall month, the South Western Cape continued to report very low January rainfall in most areas, between 40 and 60% of average.

When you note the equally poor stats from the summer rainfall region, I wonder if the country is not in another prolonged period of low rainfall, similar to the early 1930's and the 1940's ?

Can CT cope with a 4th consecutive year of low rainfall?

Don't think so. We are basically screwed if that happens and will probably see a max exodus from cape town by those that can.

Numerous recent forecasts, on various independent models, all indicate a well developed cold-front reaching the SW-Cape on Fri 9th. Some predictions go as high as 20mm, but this may just be a fluke. Probably a good opporunity to replenish (but not fill up) rainwater tanks.

As usual, more rainfall (30-50mm) is always possible over the mountains, due to orographic effects. However, there will be very little runoff from the catchments, due to low soil-moisure content. Welcome yes, but do not expect this to have any substantial effect on dam levels.
