As forecast by the South African Weather Service and as predicted by users in the forum- The Western Cape began to receive some rough weather conditions. The weather began Monday 22 June 2009 with light showers and winds beginning to increase to near 45 km/h. Though the real action occurred later into the night with the first intense band of storms arriving at around 5am to 6am on Tuesday morning. Wind gusts in excess of 30 knots were recorded and sustained winds were forecast to be near 30 knots at times during the day on Tuesday the 23 June.
The second area of storms impacted the Western Cape around 10am on Tuesday, as can be seen on the radar image below the band of storms was a squall line which had intensified off to the west of Cape Town.

The squall line in question lasted for only around 15-30 minutes and was fairly fast moving, though it managed to dump plenty of rain and bring very strong wind gusts as it passed. There are traces of small branches broken and some minor flooding in Somerset West from this squall line.
Below is a webcam capture at the time the squall line was passing, showing the extremely heavy rain and strong winds- the webcam capture makes it look like a hurricane.
