Massive rain system to soak 80 per cent of Australia this week

Every Australian state and territory will cop a soaking this week as a "blocking high-pressure pattern" dissolves after months of keeping the rain away from parts of the country.

Weatherzone reported that a "stubborn" high-pressure system near southern Australia had helped keep parts of Australia dry for the past two months.

But with that finally breaking down, a low-pressure system combining with "tropical moisture" will see rain sweep the country from west to east - along with the potential for thunderstorms, hail, and snow.

The wet weather will be concentrated mostly on Western Australia until Wednesday, Weatherzone said, before moving across central and southern Australia on Thursday and hitting the east from Friday into the weekend.

Every state and territory will receive some, though forecast models differ as to how much rain will fall.
