Mackay cops most rain in 90 years ...

Excerpt from the Courier Mail:

Two systems collide for biggest rainfall in 90 years

15 February 2008

Mackay copped a double whammy when two rain-bearing systems collided over the north Queensland city early on Friday.

Together, they produced more precipitation than most cyclones.

A storm-laden monsoon low converged with a similarly damp upper trough. The weather systems were boosted by moisture-laden, gale-force southeast and northwest winds – a key ingredient in getting such huge rainfall.

"When these winds met they had nowhere to go but up and they dragged a heap of moist air into the clouds," Weather Bureau forecaster Tony Wedd said. "When you have all these ingredients in place, you can get massive rainfall."
