A STRONG cold front approaching Perth and the South West is expected to bring wild weather conditions "similar to a strong winter storm'' including gusts of up to 125km/h.

The Bureau of Meteorology has issued a severe weather warning for coastal areas between Jurien Bay, north of Perth, to Augusta in the south, including the Perth metropolitan area, Mandurah, Bunbury and Busselton.

The Bureau says a strong cold front will cross the west coast after 11pm tonight and it will include a fast moving line of heavy showers and thunderstorms, with gusts of up to 125km/h possible in southern areas.

Damaging and locally destructive winds are possible and while winds will ease after the front moves through, the Bureau predicts they will strengthen again during Wednesday morning.

The weather system will be strengthened by the combination of a middle level disturbance that is approaching from the west, which will interact with a cold front and low pressure system developing off the west coast.

"The low pressure system will intensify on Wednesday before crossing the southwest of the state, with conditions expected to be similar to a strong winter storm,'' the Bureau forecasts.

The wild weather tipped for tomorrow follows a spectacular series of thunderstorms which swept over Perth late on Saturday, delivering large hail to some northern suburbs, including Sorrento, and dumping 26mm on Perth Airport in just a few minutes of torrential rain, but leaving other suburbs virtually unscathed.

The bad weather will be a blow to school leavers who are gathered in their thousands in the South West and Rottnest Island.

Showers tipped for First Test on Friday

Some showers are forecast for Perth till at least Friday, with the first day of the crucial third Test between Australia and South Africa starting at the WACA on Friday.

The game appears certain to start in less-than-perfect conditions with a forecast maximum of just 22C, with isolated showers tipped until late afternoon.
