Southwestern parts of Western Australia received a drenching
overnight, with some places seeing their heaviest rain in years.
A low pressure system just south of the state and an associated trough
brought rain and isolated thunderstorms to the region from Wednesday
afternoon and into this morning.
The South West copped the heaviest rainfall, with widespread falls of
30-50mm to 9am this morning. Pemberton picked up 50mm, its heaviest
rain in four and a half years, and the heaviest for May in eight
Busselton and Manjimup also saw their heaviest May rain in eight
years, picking up 42mm and 37mm respectively. The highest official
total was at Paynedale, which recorded 65mm, also the town's heaviest
fall in six years.
Rainfall totals rapidly declined further north, with Perth only seeing
11mm. East of Perth in the hills falls were a bit heavier, with
Bickley seeing 26mm, its heaviest May rain in two years.
Rain will push east today as the trough crosses the state, with places
near the coast in the South Eastern coastal likely to pick up a
further 5-10mm. However, in the wake of the system showers will
persist near the coast, with places like Perth and Bunbury possibly
picking up a further 10mm.
From Friday a high pressure system will push into the region, with
only a couple of light showers lingering about the coasts. By the
weekend it will be mostly dry, although cloud is likely to increase on
Sunday ahead of a low pressure trough.
