Canberra is expected to receive its monthly mean rainfall in a single day as forecasters predict up to 50mm of rain on Monday.

The rainfall forecast issued by the Bureau of Meteorology is just 2mm less than the 52mm mean rainfall calculated for September using 72 years of data.

Meteorologist Sean Carson said showers were expected to begin around lunchtime before intensifying towards the evening and overnight.

He said forecasters were expecting an average of 30mm across the capital, but falls could reach up to 50mm in some places.

“I think 30mm is the average mark and we may see some places above and below that,” he said.

“Either way, it’s going to be wet.”

Mr Carson said a low pressure system is currently moving through Victoria, prompting widespread rainfall across New South Wales and the ACT.

“Rain will ease back to showers after Tuesday,” he said.

“We’ll be back to dry weather from Wednesday.”

If predictions are correct, Monday will be the wettest day in the capital in more than a year.

Canberra has recorded just more than 15mm so far in September, all received on Saturday.
