Severe storms hit regions from the Illawarra to Western Sydney and north west of Sydney throughout the aftrnoon. However, it was the storm complex that moved through the south western and western suburbs that packed a punch during the evening period producing high winds and very heavy rainfall in some suburbs. Lightning at times was very active and some suburbs experienced blackouts!

At one stage an interesting radar structure developed near Campbelltown but the storms then gave way to outflow dominant activity fast advancing the activity to the east and eventually to Hornsby and north.
