Yeah, we had a storm. There are some pictures at this site which serve as material evidence. Here's the ABC's take on it. This episode of anomalous weather isn't distinguished by the volume of rainfall, the velocity of wind or the mass of the hail. It didn't surpass all-time records in any of these media of tempest. It was distinguished by the rapidity of the rate of precipitation and the persistence of the wind. Those golf-ball-sized hailstones were distinctive too.
The usual suspects emerged to proclaim the advent of Global Warming, someone suggested that a good line could be had in printing "I survived the Great Storm of Perth (2010)" T-shirts and a natural disaster was declared.
I found the most enlightening aspect of this episode to be the demonstration of the fragility of our construction and infrastructure. It just goes to show how mild the weather is here. In most parts of the world that "storm" would be a joke. I'd hate to show the data to the inhabitants of Bangladesh or the American "Tornado Alley".
