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.

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.

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
