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.

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

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.
