A weather system the Bureau of Meteorology has described as “significant” will batter WA from tomorrow, with very windy and rainy conditions tipped for much of the State.

The forecast for Perth is, in a word, wet.

After an overnight low of 13 degrees, a top of 20 is tipped for tomorrow but there is the chance of a possible storm and between 25 and 30mm of rain is expected.

Between five and 10mm of rain is tipped for Tuesday, also with a top of 20 degrees, while there is the chance of a ‘shower or two’ on Thursday before fine and sunny conditions return for the weekend.

Elsewhere in the State, strong winds ahead of a rain band will initially develop on Tuesday through inland parts of the Gascoyne, extending into the Goldfields and eastern parts of the South West Land Division, raising dust in some areas.

Winds averaging 40-70 kilometres per hour with gusts to 90km/h are possible during the day in these areas.

The rain band will bring 20-40 millimetres of rainfall about the west coastal districts with 10-15mm expected through central and eastern parts of the South West Land Division, inland Gascoyne and Goldfields.

Rain totals of 5-10mm will also extend into western parts of the Pilbara, which is unusual for this time of year.

Behind the rain band a low pressure system will approach the lower west coast on Tuesday evening, resulting in very windy conditions with showers and thunderstorms in coastal areas between Kalbarri and Mandurah.

Widespread damaging winds are possible overnight Tuesday into Wednesday morning with wind gusts up to 100km/h.

Perth long range weather forecast:

Tuesday: 13-20 degrees, 15-30mm of rain

Wednesday: 12-20 degrees, 5-10mm

Thursday: 13-21, 0-1mm

Friday: 10-23

Saturday: 11-26

Sunday: 13-29
