Weather Situation – Northern Western Australia
A high will move from South Australia into Victoria and New South Wales during
the weekend as a trough broadens over northern parts of WA. Ridging will
strengthen early next week, especially over the Kimberley and North Interior,
resulting in a fresher southeast to northeasterly flow.

Weather Situation – Southern and Central Western Australia
A high over South Australia will move into Victoria and New South Wales,
causing a ridge over Western Australia to weaken. A trough off the west coast
will move inland this morning, followed by a weak cold front crossing the
southwest corner of the State in the afternoon. The north-to-south oriented
trough will stagnate over central parts of the State on Sunday and Monday as a
weak ridge extends over the west coast. A moderate to strong front may reach
the west coast on Wednesday.

Forecast for the rest of Saturday 9 September
Mainly light showers with the chance of thunderstorms in the Central West,
Great Southern, Lower West and western Central Wheat Belt, largely clearing by
the late afternoon. Chance of showers in the remainder of the Lower West,
western Great Southern and northern South West. Showers and thunderstorms
possible through the day in the remainder of the South West as well as the
South Coastal District and South East Coastal Districts. Areas of fog in the
morning inland from the Gascoyne and west Pilbara coast.

Forecast for Sunday 10 September
Light showers possible about the southwest coast. Chance of high-based
thunderstorms producing little to no rainfall over the east-central Goldfields
and adjacent parts of the Eucla and South Interior. Cloud clearing in the
afternoon through much of the Lower West, South West, Central Wheat Belt and
Great Southern.

Forecast for Monday 11 September

southeastward through the Goldfields and Eucla, and in the South West, with
mainly sunny skies for the remainder of the State.

Forecast for Tuesday 12 September

likely in the South West. Areas of fog in the morning over the southern Central
West, western Wheat Belt, Perth hills, Great Southern, and inland parts of the
South West and South Coastal Districts. Slight chance of late showers in the
