Perth may reach its average rainfall for July.
It might be dry July for some West Australians but in terms of weather, the last week of July is set to create a splash.
The western and southern parts of the state should prepare for a number of downpours over the next week, and they may be as frequent as every day according to Weatherzone meteorologist Brett Dutschke.
Mr Dutschke said both the moisture and the frequency of cold fronts have increased in the past few days with the assistance of warmer than normal seas.
He said this trend should hold on long enough for some areas to get showers every day until August.
"With less than a week to go, an average July is still possible for a large area due to the prospect of a few more fronts," he said.
"Between now and this time next week, 50 to 100mm is likely from Jurien Bay to Northam to Albany. The Bunbury to Margaret River area has the highest chance for 100mm."
He said that Perth has had rain on four of the past five days, amounting to a total rainfall of 27mm. This brings the total for the month to 100mm, just short of the monthly average of 170mm.
"Rain will be widespread, but not be nearly as heavy as far as Merredin, where 10mm to 20mm is most likely. Not a lot but enough to take it near its monthly average of 51mm," he said.
He said that the southeast coastal district would have even less rainfall this week, following a recent dry spell, while Salmon Gums may still achieve its first wetter than average month since January, and its wettest July in three years.
