My wife reported the sky going inky black, and golfball hail bouncing off her 12th storey window during a meeting...with an awesome roar. She also said alot of the city is without power.

Local weather enthusiasts page with what looks like a dirty great HP meso (not the first squall, the later pictures) and initial hail shots.

And in case you are wondering why I'm taking such notice of Perth (besides my wife living over there)...our house is probably 2km away from the 6cm hail report...and golfballs were reported 1km to the north.

My sister in-laws car copped a couple of dents near Greenwood this afternoon looks like she was lucky.
I never encountered any hail the whole time I was in Perth (app 5 years). My misses kept telling me it used to hail there.
Guess I'll have to believe her now :)

The number of warnings the Perth BoM issued during the afternoon and evening was the most I have ever seen for WA.

A really nice hailstorm setup

Both Melbourne and Perth are not known for giant hail. I am thinking El Nino coupled with a hot summer is behind these storms.
There was a huge storm over the West of the South Island a couple of days back.
