A cold front will approach south west WA Saturday afternoon, moving across the South West Land Division, southern Gascoyne and the Goldfields during Sunday, bringing cold, gusty and showery conditions with possible thunderstorms and small hail.
These cold, gusty and showery conditions will continue Monday as a low-pressure system develops near the south coast and moves east during Tuesday.

Daytime temperatures will be well below average across western WA, with places in the south struggling to reach double figures. It will feel even colder due to fresh, southerly winds.
Hazardous surf with coastal erosion is possible along the Albany and Esperance coast on Monday and Tuesday.
Unseasonal rain in the north
Typically, during this time of year the Pilbara and the Kimberley are in their dry season, but cloud bands can still bring unseasonal rain.
A band of cloud currently causing some showers will increase to rain during Monday and Tuesday in central and eastern parts of the Pilbara and northern Interior.
Daily rainfall totals of 20-50mm are possible, with isolated heavy falls up to 100mm, particularly near the east Pilbara coast during Monday and Tuesday. The rain band may even reach Broome by mid next week
