Overview
- Forecasters warned Monday that a large, slow-moving pattern of upper-level lows and low-pressure systems is developing across eastern Australia and will drive widespread rain, thunderstorms and strong winds this week.
- The Bureau of Meteorology and weather services say parts of New South Wales, southern Queensland and eastern Tasmania could see very heavy totals, with some NSW coastal areas possibly receiving 100–150mm or more depending on coastal-low development.
- Authorities have issued hazardous surf warnings for several northern NSW coasts and are closely monitoring flash‑flood and river flood risk in already saturated catchments in north‑east NSW and south‑east Queensland.
- Severe thunderstorm threats include damaging winds and large hail for inland NSW and south‑east Queensland, while Western Australia faces a separate midweek cold front followed by a potentially stronger low over the weekend.
- The rain will likely bring drought relief for some agricultural areas but will also cause travel disruption and flooding; residents are urged to follow BoM updates and local emergency advice as forecasts may change over the next 48–72 hours.
