Rain on the way for WA

A low pressure system approaching from the Indian Ocean will spread rain and thunderstorms into WA on Tuesday, with up to 30mm expected for parts of the west coast.

The low is currently intensifying over the warmer than normal waters of the Indian Ocean. Sea surface temperatures are running more than two degrees above average, which is providing extra moisture to the low as it tracks towards the WA coast.

Rain will develop along the west coast late tonight and become heavy at times during Tuesday morning. The heaviest rain will fall over the Central West district where thunderstorms are also possible, bringing widespread totals of 15 to 30mm. For Geraldton, this will be the first recordable rainfall of the month.

For residents in Perth, it will be a wet morning commute on Tuesday with periods of rain, which will then ease through the day. The city can expect 10 to 15mm of rain by the day's end.

The low will continue to track east through the day, spreading rain to the Central Wheat Belt, where up to 10mm is expected. The low pressure system will then track south and east into the Bight on Wednesday, with cooler southerly winds following in its wake.

Perth is only expected to reach a top of 17 degrees on Tuesday and 18 on Wednesday, a cooler change from the 20 degree plus temperatures that were being experienced last week.
