Oh, yes, Melbourne weather is unpredicatable... I remember on that day we had that strom that flooded everything that it was really warm and sunny at first and than bam! All this rain starts coming down, then hail and thunder + gale force winds. We had plenty of flooding and fallen trees at our place! What fun it was trying to unblock the drains while water is pouring into the garage and creeping towards your house!

I was upgrading my computer to Fedora 8 when the power went out too!
