Funny you mention this as we were discussing the flowers in Namaqualand with an America Peace corp member in my office two hours ago,...


This is our back garden and we were just saying how the flowers have had a poor showing over the past three years, but with the current rains we expect and awesome display........ In about a 3-4 weeks from now it should look quite stunning....

We in Omund just over the border are getting way more tourists passing through our town and were of the conclusion that there will be a small "overflow" of flower power tourists popping up to our part of the woods...

Spoke with my mate this morning in Springbok, he is the Greenkeeper at the Springbok Golf club, reckons they lost a few tree's out on the course with the gales...
 
A well developed frontal system is approaching the SW-Cape, and is expected to make landfall later on Mon 29th, persisting into Tues 30th. Though it looks quite impressive on the charts and satellite image, it is not expected to bring huge amounts of rain like last week's storm.

Edit: The next significant series of cold-fronts are likely sometime starting on Sun 4th Aug.

Somewhat alarmist prediction by the SAWS: https://www.news24.com/SouthAfrica/...-rains-expected-for-w-cape-on-monday-20190728
The Western Cape, which is in the grip of a cold snap, is expected to be battered by gale force winds and heavy rain from Monday.

The public is advised to take note of the following, as provided by the South African Weather Service

Extremely high fire danger conditions are expected over the central and southern parts of the Northern Cape, Central and Little Karoo, Cape Winelands, Breede River Valley of the Western Cape as well as the central and western parts of the Eastern Cape.

Gale force north-westerly winds of 65-80 km/h are expected between Table Bay and Cape Agulhas from Monday evening into Tuesday afternoon.

Heavy rain leading to localised flooding is possible over the Cape Metropole, the western parts of Cape Winelands and Overberg District of the Western Cape on Tuesday from early morning.

High seas with wave heights of six to seven metres are expected between Cape Columbine and Cape Agulhas on Tuesday from early morning ,spreading to Plettenberg Bay in the afternoon, and subsiding on Wednesday morning.

Oh, how nice, considering I'm moving tomorrow
 
Winds up markedly already( and no, not in my pants, before any wise cracks get in).Just a taste of things to come ...

How does rainy and windy conditions lead to high fire danger alerts?

It is what happens ahead of a frontal system that leads to the fire danger warnings. Off shore winds and winds out of the interior tend to dry out the air ahead of the front reducing the relative humidity which means higher probability that should a fire arise it will be more difficult to contain.

Thanks for that @Geoff.D

Most of the SW-Cape is wet enough not to have a high fire-risk, but peripheral areas such as the Tankwa Karoo and Little Karoo are at risk.

The hazard depends to some extent on the synoptic outlook, and today there is definitely a large time delay (about 18 hours) between the onset of the winds, and the arrival of the rain. In any case the amount of rain predicted (away from the mountains) is rather low. This is pretty clear from the charts this morning:

Dam levels have also been updated earlier - http://www.capetown.gov.za/Family and home/residential-utility-services/residential-water-and-sanitation-services/this-weeks-dam-levels

72.1% :D

Those are the "daily" levels, and are always updated early. BTW, I posted the link since it mentions areas outside of the SW-Cape. The Gouritz catchment is still critically low.

The weekly report has more fancy charts, and takes longer to produce. Oh, they are also out! See: http://resource.capetown.gov.za/doc...ity research reports and review/damlevels.pdf

CoCT up 8.1% in one week, and way beyond the danger zone! Highest (seasonal) level in more than 3 years, and almost at the peak last seen at the end of 2015!

Brilliant. Really hope there are 1 or 2 more similar cold fronts before winter ends.
 
That would be a really good outcome. The season was late and things were looking gloomy till last week, so holding thumbs for WC.
 
Was quite surprised to learn that the De Bron dam that feeds Hermanus is only on approximately 44%. They are busy drilling more boreholes there.
