Southern parts of Western Australia are in for more wild weather over the next 48 hours after Perth recorded another spell of heavy rain overnight.
The Department of Fire and Emergency Services (DFES) has issued a severe weather warning for parts of the South West and the Lower South West, with a cold front due to sweep across Saturday evening.
"Thunderstorms and showers associated with the front may bring damaging winds to 100 kilometres per hour and could cause damage to homes and property in the warning area," DFES said.
"Isolated gusts in exposed coastal areas south of Augusta may reach 125 kilometres per hour.
"Moderate to heavy rainfall is possible and may lead to localised flooding."
DFES said residents in Bunbury, Busselton, Manjimup, Margaret River, Augusta, Dunsborough and surrounding areas needed to prepare for the bad weather.
Meanwhile, warnings for possible minor flooding have been issued for parts of the Perth metropolitan, South West, Lower South West and Great Southern regions.
DFES said the warnings affected people in Bunbury, Preston River, Busselton, Mandurah, the Margaret River and Blackwood River catchments, the Murray River basin catchment — including the Serpentine area — and the Harvey River catchment.
The department advised people to relocate livestock and equipment early and urged motorists to drive to the conditions.
It comes after Perth received almost 20 millimetres of rainfall from a cold front overnight.
The rain was heavier elsewhere, with Myalup south of the city recording 47.7mm and Jarrahdale to the south-east getting 46.4mm.
A wind gust of 113 kilometres per hour was recorded at Busselton Jetty, the Bureau of Meteorology (BOM) said.
Another, stronger cold front is expected to move in on Sunday evening and early Monday morning, with damaging winds and moderate to heavy rain forecast south-west of a line Lancelin to Albany.
Rainfall totals remain below average following a late start to winter — but it is hoped it will even out over coming days.
"We are still below average for winter but I am hoping that the next few days, in addition to this one overnight, will help us get to a more average total rainfall," BOM duty forecaster Noel Puzey said
Mr Puzey said Perth had recorded around 105mm of rain so far during August — with 133mm being the average monthly figure.
"We are making some progress on the catching up on the very low rainfall we've received during this year," he said.
"We have ended up with a winter which is below rainfall amounts to what we should expect."
Farmers and grain growers have received some rain — although it was too late in the season.
"Most agricultural districts have received rain over the last week, this particular band will also push through the northern and eastern parts as well and they'll get a little bit out of that and they're likely to get some out of the one on Monday night into Tuesday."ABC
