Wild weather ripped across the southern half of the State yesterday and throughout the night, with heavy rain and strong winds recorded in several towns and suburbs.
The strongest September wind gust on record - 130km/h - hit Cape Leeuwin at 10.45am yesterday.
The strongest gust in the metropolitan area was 93km/h at Ocean Reef later in the day. Early this morning a wind gust of 83 km/h was recorded at Rottnest Island about 1am.
The State Emergency Services received two callouts minor storm damage overnight, a Department of Fire and Emergency Services spokesman said.
Despite strong winds and storm activity Perth saw just 11mm of rain since 9am yesterday to 7am this morning.
Ravenscliffe recorded 27mm of rain between 9am and 4.30pm, while 21mm fell in Dwellingup and 20.2mm in Mandurah.
SES volunteers responded to 15 calls for help yesterday, most related to water damage in Rockingham and Mandurah.
The wild weather also caused problems for planes at Perth Airport with a number aborting their landings because of strong winds.
But all planes landed on the second attempt, airport sources said.
Planes were also slowed by air traffic control in the afternoon as the front moved through.
A Weather Bureau spokeswoman said the bad weather was caused by a strong cold front moving through the South West.
Perth has recorded more than 84.6mm of rain this month, making it the wettest September in 16 years.
The front has moved inland with showers expected along the Eucla Coast and Great Southern area, weather bureau forecaster Greg Browning said.
Showers will ease in Perth this afternoon with another system bringing more shower activity through tonight, Mr Browning said.
There will be brief breaks but coastal showers will be a feature through the South West right through the week, he said.
