June may have started dry over Western Australia but widespread heavy rain predicted by weatherzone during the last few days of the month should lift totals above average across most of the state.
According to FarmOnline Weather, Wednesday already brought the heaviest falls in a year to some regions including 45mm at Dwellingup and Pinjarra.
Nangeenan in the Central Wheatbelt received 27mm, their wettest day in three years. Further north, Newman in the Pilbara picked up 36mm, their heaviest June fall in 38 years worth of records.
The rain eased on Thursday but will increase again late Friday as a strong cold front approaches from the Indian Ocean.
The front will be the first in a series of four or five due to sweep over southwest WA during the next week.
Each front will bring a burst of strong winds and widespread showers. By the middle of next week as much as 100mm of rain is likely to fall on the west coast south of about Jurien while the Wheatbelt can expect up to 50mm.
