Perhaps this too - Patrols to prevent farmers from stealing water as dams drop faster

You don't expect actual journalism from IOL do you? Alarmism, tenous factual connection. Its back to Day Zero paranoia...

I saw the billboards and headline on the front page of the Cape Times in the shop this morning. Wasn't going to bother to read it until you posted, waste of time...

For the record: The lower Berg River where the water theft occurred, is downstream from all of the dams that supply the City of Cape Town. Misverstand dam was in a crisis, but the water released last week should have helped. That came from the (upper) Berg River dam, whose level did reduce accordingly.

BTW, Steenbras Upper dam has no natural outlet, and is used only for pumped storage. I have no idea why the level is lower, but it has nothing to do with farmers (or water consumption), most likely a misprint.

Edit: Releasing water down a dry river bed is a rather inefficient method of transfer: https://www.news24.com/SouthAfrica/...-to-make-it-to-misverstand-dam-mayor-20180424

I seem to recall something about water being transferred a week or two back.

Its probably like when a beer delivery truck overturns. Bystanders see all that precious liquid being spilled, and quickly help themselves.

Subsititute farmer and river water release, and you get the picture. IMO, if there was no water release, there would have been nothing to steal...

We have an open field in our neighbourhood and it has been cordoned off today. I asked around and it seems that CoCT is building a "flood water storage "pond" to capture rainwater". Not sure how long this will take to complete but surely something like this should be built before the start of the rainy season. This is the same neighborhood that suffered flooding in 2013 along with Vergelegen Mediclinic.

Location where they will be putting in this stormwater collection pond.

I don't recall any consultation being done and what the work entails or what the completed work will look like. 20180424_162015.jpg

I learned long ago that words like tomorrow should be avoided online. I also get dates mixed up, so I use weekdays as well (at the risk of being redundant). Even some major websites don't do this properly.

All forecasts indicate that it will rain over CT later on Wed 25th, overnight into Thurs 26th, and clear slowly thereafter.

Further rain is possible over the long-long weekend (particularly Sun 29th). However none of the models have been consistent, so I can't even be sure of the dates, never mind amounts of rain.

I'm speechless!?

If you mean AI = computers, then of course they do.

If you mean AI = neural networks, or fuzzy-logic, or something trendy, then no, it won't work...

Throwing jargon around doesn't make things magically happen. See: https://en.wikipedia.org/wiki/Applications_of_artificial_intelligence

Some folk are trying to use neural networks. Probably turn out to be a fancier statistical downscaling.
I prefer a fully dynamic description.
But yes it is a trendy thing to do with all these big data "scientists" hanging around.
Take a look at what IBM SA are planning to do.

What a load of rubbish. Wow. How can you make such a retarded statement?

You seem to like making snarky comments. Stop it.

I have been involved in weather my whole life, and computers for most of that. I found your original post fits your own 'description', but I tried to give a polite response in my reply.

You have failed to provide a shred of evidence for your suggestion, and I have not read anything which backs it up.

Edit: Some research-scale work has been done by IBM: https://researcher.watson.ibm.com/researcher/view_group_subpage.php?id=6572

Edit: Specific statistical improvements can be made over certain time-horizons, but these are enhancements to existing weather models, not substitutes.

Edit: In the case of SA we have significant budgetary and logistical issues around detailed weather data collection, never mind forecasting.

I meant IBM SA specifically. They plan to make things operational. Of course much of it is likely bluster; and to put some use to their new cluster.

In terms of statistics, yes those play a role in models as well, but I would say a downscaling (e.g. CSAG's work) is not a dynamic model anymore.
Also I mentioned neural networks because there is some research into using them for forecasts and in fact sidestepping the models.
This has come primarily from the IT sector though; and are dismissed by the meteorologists rather rapidly.
