Update: Upper-trough and frontal-low SW-Cape 25 August 20


The storm arrived over Cape Town in the early hours of this morning (03Z on Sat 25th), almost exactly as predicted by the models. Strong wind gusts and heavy rain showers are noticeable at dawn (7am).

The Cape Town radar is working, and shows a few isolated storms passing directly overhead. I just saw flashes of lightning in the direction of Simonstown, and the CT radar confirms a storm cell with intensity > 50 dBZ passing over that area (0440Z).

The main front has already passed over Cape Town (03Z on Sat 25th), but heavy showers are likely at times for most of today, as the upper trough moves overhead.

The weather in Cape Town should start to clear on Sun 26th, as the low moves rapidly away to the east (offshore).
