Severe weather warnings for damaging winds and dangerous surf are current in five states and territories – South Australia, Victoria, Tasmania, New South Wales and the ACT.
Conditions will ease for some parts today and worsen on Wednesday night into Thursday morning, as a complex low pressure system moves towards the coast.
Heavy rainfall is expected in some regions, with isolated major flooding possible in catchments in southern NSW, northern Tasmania and north-east Victoria. Minor to moderate flooding is possible elsewhere in the affected areas.
The Bureau is monitoring the situation closely and will update its forecasts and warnings regularly.
Communities are encouraged to stay up to date with forecasts and warnings via the Bureau's website and BOM Weather app and follow advice of emergency services.
