It's set to be a big week of rainfall for southwest WA thanks to a number of cold fronts crossing the region. The most significant of these fronts is hitting on Tuesday morning and it's expected to deliver as much as 25-50mm for the west coast including Perth, with 5-15mm possible for the Central Wheatbelt favouring the western half. Most of this rain will occur during Tuesday morning with isolated showers during the afternoon. The bad news is that this front is likely to be accompanied by severe weather. Damaging winds are possible ahead the front on Tuesday morning with squally storms potentially generating powerful winds also. Damaging winds with gusts over 90kmh are strong enough to bring down trees and power lines.
The next front is due on Thursday with another 5-15mm expected for the west coast and lighter falls further inland. By the end of the week as much as 50-100mm could fall on the west coast with anywhere between 10-20mm for the Wheatbelt.
This comes on top of heavy rain just last Friday where Perth saw 57mm! This brings Perth's June rainfall so far to 128.2mm, just 6.5mm short of the June monthly average. Needless to say, many parts of the southwest will have recorded above average rain for June by the end of the month.
