Mandurah was drenched in a downpour overnight that was six times the monthly average, making it the highest daily January average ever recorded in Mandurah.
This makes it the highest daily January rainfall ever recorded in Mandurah, smashing the record of 63.4mm, which fell on January 25 seven years ago in 2006.
At 8am this morning, Mandurah recorded 79.6mm of rainfall, well over the 12mm January average.
Bureau of Meteorology spokesperson James crow said the rainfall is from Cyclone Joyce that passed between Port Hedland and Broome.
“Events associated with cyclones are likely to happen this time of year and they will come down the South Coast and will likely bring down more rainfall,” Mr Crow said.
“We are seeing the remnants of Cyclone Joyce. Conditions are starting to weaken now.”
Mr Crow said there were chances of thunderstorms but they were more likely to be inland of the coast.
“By Thursday, most of the weather would have disappeared,” Mr Crow said.
Last year, the South West had a wet start to the year due to thunderstorm activities in the tropics, Mr Crow said.
”That was due to a cloud ban over the South West,” he said.
“Up in the tropics it can get active with thunderstorm activities and that can come down the South West.”
