I woke up to the storm lashing the house. Had to close the front door (yes, we leave it open at night for the dogs ).
Anyway, when waking up this morning, I opened it to find my one dog sitting on the doorstep - silly girl was running in the storm and I didn't know

Very heavy rain was recorded in many places around CT last night. I don't have the SAWS official figures, but in Kenilworth we had 33mm overnight, plus 10mm during the day yesterday.

The SAEON Dwarsberg and Constantiaberg sites recorded rainfall rates of 20mm per hour around 1am this morning. The recording period for those is up to midnight, with 47mm for Dwarsberg, plus at least 60mm this morning, so well over 100mm during the last 24 hours.

It will be relatively dry for the next 36 hours, with further heavy rain from another cold front arriving late on Sat 2nd.

The following week (Mon 4th to Fri 8th) looks rather dry, with the rain picking up again in the second week in June.

Edit: The SAWS reported a few impressive rainfall totals in the 24 hours to 8am on 1st Jun: http://www.weathersa.co.za/media/data/climate/nr_daily_rai.pdf

Highest include Kirstenbosch 72mm, Ceres 45mm, Jonkershoek 39mm, Grabouw 35mm, etc. Areas away from the mountains received much lower amounts.

Edit: The 10 day and monthly rainfall figures also make for interesting reading:

The broad rainfall for May 2018 was close to the long-term average, certainly much better than 2017.

The canal is nice and full.

Seems like almost all the storerooms in the basement are flooded.

Dear Sir, there's a meeting in the town square at noon. Please bring 2 bushels of corn if you can. Sincerely.

I see Theewaterskloof cracked 20% this weekend...
 
As predicted, the AAO index went positive, meaning the westerly winds moved south of where the band should be this time of the year. Weaker cold fronts sliding past the country was the outcome.
The AAO index is expected to reach zero on about the 16th June, and then go fairly sharply negative soon after. This means the westerlies return to where they should be and maybe even move further north. So the latter part of June should see more cold fronts reaching our shores and generally a normal to wet latter part of June after the 16th.

A compact but well developed cold-front passed over Cape Town early this morning (Sat 9th). I awoke to a torrential shower just before 8am. The rain gauge here in Kenilworth showed 30mm overnight (seems to have stopped now). The SAEON Dwarsberg mountain catchment site showed over 40mm during the same period.

Some showers are likely during the rest of today, but after that will be dry for a prolonged period. The next major cold-front is due at the end of next week (Thurs 14th onwards).
 
Numerous forecasts show a large and slow moving cold-front making landfall over the Western Cape on Thurs 14th. This will be accompanied by strong winds, and a sharp drop in temperature on Fri 15th, when snow is possible over the highest mountain peaks.

The exact amount of rainfall is hard to predict, but it is certain to exceed 50mm in places, causing localised flooding. Cumulative totals in excess of 100mm are likely over the mountains.

This charts shows the potential rain during the first day of the front (Thurs 14th).

Great, going away from Thursday - Sunday to Tulbagh area. It is going to be a wet braai.
 
I'm keeping an eye on this and it looks good. The ride I am doing on Saturday is in Worcester and things seems pretty good there Saturday in the A.M. while being wet on the Cape side :cool:
