A tropical cyclone a long way off Western Australia's north-west coast has intensified into a category three system.
Severe Tropical Cyclone Victoria is moving in a southerly direction in the open water, about 555 kilometres south south-west of Christmas Island.
The island had 52 millimetres of rain in past 24 hours.
The Bureau of Meteorology does not expect Victoria to directly affect the island or the Australian mainland.
It is expected to weaken by Thursday afternoon into a tropical low.
The bureau's Brad Santos says Perth may experience rain from the system.
"Later on in the week and into the weekend, what's left of the system we might get some light rain or some shower activity over southern parts of the state," he said.
"We're not expecting any impacts from the tropical cyclone on the WA mainland."
