Carwoola has had a very dry start to the year. So it was very pleasing to score 9.8mm of rain on the 2nd of March. This was enough to get the Creek running.
The BoM forecast for the weekend of 4-5 March has been up and down over the last few days and had ended up in the low end of their estimates. Early on the 4th I consulted the radar ...
a fair expectation is about 40mm in a normal March.
Another way of thinking about this is to look at the number of years in which the rainfall was in a few classes. I hope this chart is comprehensible: it show that the commonest class is 10 - 39.9mm with 40 - 59.9mm not far behind. Again about 40mm would be a fair expectation.
