Rain and storm for Cpt

It's been nearly non stop rain for nearly 2 days here in Constantia. Thank the Lord.
 
The SAWS reports a few substantial rainfall numbers for the 24 hours to 8am on Wed 3rd, but areas away from the mountains received almost nothing: http://www.weathersa.co.za/images/data/climate/nr_daily_rai.pdf

Highest include Kirstenbosch 80mm, Jonkershoek 29mm, Paarl 28mm, Ceres 26mm, etc.

Our gauge in Kenilworth had another 19mm this morning (in addition to the 40mm yesterday), making a cumulative total of around 60mm, from a single 'weak' cold front. The majority of this is due to orographic effects, being about 5km downwind of Table Mountain.

Edit: Link to daily dam levels that @air refers to below: http://www.capetown.gov.za/Family a...and-sanitation-services/this-weeks-dam-levels

Edit: Big 6 dams up 4.3% in the 4 days from Mon 1st to Thurs 4th.

Real dry up here in Sutherland. Blue sky soonbas we came out of the tunnel yesterday.

Slight clouds showing on the horizon now after sunset. Pity we're leaving tomorrow. Snow would have been awesome.

What you doing up there, didn't know you a astronomer enthusiast like myself :cool:
 
any one have dam level comparison to last year this time ?
 
Steenbras and Wemmershoek lagging behind.. but overall thumbs up.

That was a very weak cold-front that just brushed the extreme SW-Cape. If you were not in the South Peninsula, or near the mountains, you would barely have noticed.

Edit: 8.5mm in our gauge in Kenilworth this morning.

Another few fronts are coming in the next few days, but the overall trend is drier. The next potential series of cold-fronts is possible in the third week of July.

Dam levels are certainly better than the same time last year, but 2018 had a very wet July, so we may soon be lagging behind.

Non-irrigated agricultural areas such as the Swartland have been badly hit by the lack of rain.

Another weak cold-front brushed the extreme SW-Cape yesterday (Sat 6th). For most it was a non-event, but it did produce significant rain near the mountains.

We had 24.5mm in our gauge in Kenilworth.

The SAEON Dwarsberg (Jonkershoek) mountain catchment station recorded 95mm.

The level of the Berg River Dam rose by more than 1% overnight, making a total increase of exactly 10% in the first 6 days of July (from 78.8% to 88.7%)

The outlook for the next 7-10 days is much drier (until the third week in July).

If memory serves, last year they actioned the transfer of water from berg to twk at a rate of 300m litres per day, has that been turned on yet? Berg should hit 90% today.

AFAIK the transfer of water from the Berg River Dam to Theewaterskloof happened at a high percentage, and during rapid inflow. Not quite there yet, but CoCT will preferentially juggle the domestic use first.

No official announcement, but the level of Theewaterskloof (and the other dams) have risen faster than the Berg River Dam in the past 24 hours: http://www.capetown.gov.za/Family and home/residential-utility-services/residential-water-and-sanitation-services/this-weeks-dam-levels
Mon 8th 89.5% and 50.4% average 59.8%
Tues 9th 89.9% and 51.1% average 60.5%
Increase 0.4% and 0.7% average 0.7%

Edit: Also see the 5 year view, which gives a broader analysis: http://resource.capetown.gov.za/doc...ity research reports and review/damlevels.pdf

There will be a very long wait till the next major cold-front, probably around Wed 17th or Thurs 18th.

Looks like the 18th at this stage. And a more significant one on the 22nd, but that's still far out.

Rather disappointing outlook. The models have 'flipped' into a different state, with a weak front brushing the S-Cape on Thurs 18th, and a deep low far to the SW having no effect on land for several days...
