Rain forecast as record for wettest June looms

According to the Bureau of Meteorology website, there is a 95% chance of rain in Bunbury on Sunday, with 5-10mm expected.

And there is a 100% chance of rain on Monday, with a further 20-35mm expected to fall.

Great news for ducks, and farmers.

The showers are expected to continue on Tuesday with a further 5-15mm predicted before the rainfall eases on Wednesday with only 1-4mm of rain predicted by the bureau.

Perth is set to record its wettest June for five years inside the first 19 days of the month - with another cold front poised to deliver a soaking to the city.

And the metropolitan gauge may also have received its average rainfall for June by Tuesday.

The latest in a series of cold fronts that have rolled across the coast is set to arrive from late Sunday night and deliver as much as 40mm of rain to Perth on Monday.

There could be up to another 23mm across Tuesday and Wednesday.

“Perth is probably going to start seeing the front from about midnight on Sunday,” Bureau of Meteorology duty forecaster James Ashley said.

“When it hits there is going to be plenty of heavy rain and also likely some squally winds to go with it.

“The rain is going to be seen pretty much right across the west and South West of the state.”

The rainfall will spread far enough east to deliver up to 10mm to farming areas like Cunderdin and Merredin but there will probably only be weak rainfall (5 to 10mm) east of Albany towards Esperance.

But Perth needs only another 29mm to post its wettest winter since 2012, when 140mm fell in the metropolitan gauge.

Thanks to solid falls in both the first and second week of the month, Perth already has 80mm for June - significantly more than the monthly total for 2013 (44mm) and on track to breeze past 2014 (93.6mm), 2015 (100.4mm), 2016 (109.4 mm) and last year (88mm).

If the rainfall next week is on the higher end of what is forecast, then Perth would also pass its monthly average for June since 1993 (124.4mm).
