A trough moving east across South Australia combined with a low pressure system in the Great Australian Bight to bring widespread rain and thunderstorms to south-eastern Australia from Thursday. The Bureau of Meteorology initially forecast 30 to 50mm for Melbourne over several days, with showers and storms also likely in Canberra and Sydney on Saturday. By Saturday, the system had intensified, prompting a flood watch for most of Victoria. The Bureau expects the heaviest falls of up to 90mm in parts of the state, with already sodden riverine catchments raising the risk of flooding. Transport delays and disruption are expected across affected regions.

The Bureau of Meteorology has issued a flood watch for most of Victoria as a severe weather system continues to drench the state, with falls of up to 90mm expected in some areas. The warning covers the north-east, central, south-west, north-west, and parts of Gippsland, prompting alerts of transport delays and disruptions.

Analysis
Why This Matters
- Residents in flood-prone areas face potential property damage and road closures.
- Transport networks in Victoria may experience significant delays, affecting commuting and freight.
- The flood watch indicates a heightened risk of riverine flooding, which could escalate if rain continues.
Background
The weather system developed from a trough over South Australia merging with a low pressure system over the Great Australian Bight. Initial forecasts warned of heavy rain and storms across Victoria, New South Wales, and the ACT. By Saturday, the focus shifted to Victoria, where existing wet conditions increased the likelihood of flooding.
Key Perspectives
Bureau of Meteorology: Issuing flood watches and advising communities to prepare for potential flooding and disruption. Residents and commuters: Facing travel delays and the need to monitor local warnings for rising water levels. Emergency services: On standby for possible flood response, particularly in riverine areas.
What to Watch
- Rainfall totals over the next 24 hours, particularly whether they exceed forecast amounts.
- Any escalation of flood watches to flood warnings for specific catchments.
- Updates on transport disruptions and road closures across Victoria.
