Just as a powerful weather system that brought wild conditions to Western Australia clears the state, another round of wet and stormy weather is set to hit the South West, including Perth.

Showers will continue on and off for the rest of May but the rain will ramp up towards Friday as a new cold front moves through.

The Bureau of Meteorology (BOM) is forecasting rainfall in the double digits for coastal and inland areas.

"We've got a cold front coming on Wednesday, which is looking like quite a weak feature, and then another more significant one which will arrive late Thursday and into Friday morning," duty forecaster Jessica Lingard said.

"The heaviest rain will be along the coastline as it first approaches, but we are expecting rainfall to move a fair distance inland — 10–20 millimetres through the agricultural areas and towards the Goldfields."

Rain forecast but destruction unlikely

The front is expected to affect an area south-west of a line from Kalbarri to Esperance on Thursday and Friday, before the rain reaches further east into the Goldfields by Saturday.

Thunderstorms are possible with the front and winds will pick up, but Ms Lingard said it would not have the same impact as .

That was the result of a cold front mixing with the remnants of an out-of-season cyclone, whipping up wind gusts up to 132kph — consistent with a category 2 cyclone.

"Winds with this system could be quite gusty as it does cross the coast, however nothing like what we've experienced in the last couple of days," she said.

"The system that passed on the weekend , very significant in terms of wind gusts, so we don't expect it to be anything like that."

The wintry conditions will extend into the weekend, as chilly onshore winds in the wake of Friday's cold front bring more showers and cooler temperatures.

Perth on track to reach rainfall average

On the rainfall front, Perth had a promising start to the month, recording 32 millimetres of rain — about a third of its May average — in the first week.

The city then cruised through a run of 16 dry and predominantly sunny days.

Since Sunday it has been making up for lost time, collecting another 26mm, which brings the total so far this month to almost 60mm.

The current forecast has Perth receiving 6-15mm on Thursday, 15-35mm on Friday, 0-4mm on Saturday and 2-4mm on Sunday, putting the city on track to reach its May average.

Perth forecast
Wednesday: Possible shower. 0-2mm possible, 9-21C
Thursday: Showers, possible late storm. 6-15mm possible, 11-20C
Friday: Possible storm, heavy falls. 15-35mm possible. 12-19C
Saturday: Shower or two. 0-4mm possible, 6-16C
Sunday: Showers. 2-4mm possible, 9-19C
