BOM

Issued: 2pm AEDT 24 October 2022

Major flooding continues along a number of rivers in northern Victoria and much of New South Wales. Rain and thunderstorms continue for eastern and south-east Australia, increasing the flood threat further. Severe Weather Warnings are current for Heavy Rainfall for parts of New South Wales, South Australia and Victoria, while rain has cleared in south-east Queensland.

In South Australia, another low and trough is bringing widespread rain and thunderstorms with some heavy falls to eastern parts of South Australia and much of Victoria and southern New South Wales today. This low will deepen over southern New South Wales today, moving slowly across south-east Australia today and tomorrow, bringing widespread rain and thunderstorms with moderate to heavy falls possible.

Severe thunderstorms are likely this afternoon and evening across much of southern Queensland, and inland New South Wales, and possibly northern Victoria with heavy rain, damaging winds and large hail.

Showers and thunderstorms will contract into eastern Queensland and New South Wales on Tuesday with showers continuing across Victoria and Tasmania. Severe thunderstorms are likely again on Tuesday in north-east New South Wales and south-east Queensland.

Further west another weak trough will bring showers and possible storms to southern Western Australia and South Australia.

Major Flooding is occurring or forecast to occur at Echuca Moama (above 1993), Barham, Kerang, Moree, Gunnedah, Narrabri, Hillston, Hay, Condobolin as well as a number of smaller towns, impacting roads, rail, homes, properties, businesses and agricultural land.

Flood Watches are current for New South Wales, Victoria and Tasmania. Further Flood Warnings will be issued in coming days as rivers respond to rainfall and renewed flooding develops.

At Echuca, river levels were above the 1993 level of 94.77m, peaking near 94.9m today. At Moree, river levels peaked higher than the March 2021 event. At Lismore looking at moderate flooding later today below major.

As at 9.00am Monday, Major Flooding in NSW is occurring on the Gwidir, Mehi, Peel, Namoi, Bogan, Lachlan, Murrumbidgee, Murray, Barwon, Darling, MacIntyre and Edward Rivers.

As at 9.00am Monday, Major Flooding in Victoria is occurring at Loddon River and Murray River. Minor to Moderate Flooding is occurring across many other rivers in Queensland, New South Wales, Victoria and Tasmania.

Hazardous Surf Warnings are current for parts of south-east Queensland and north-east New South Wales.

Widespread 100 to 200 mm has fallen in far north east NSW overnight with rain slowly easing there today. The highest rainfall totals in the 24 hours to 9.00am AEDT Monday include:

233 mm at Alstonville, NSW

215 mm at Goonengerry, NSW

196 mm at Doon Doon, NSW

178 mm at Repentance, NSW

159 mm at Tuckombil, NSW

The weather is likely to become more settled mid-week, although showers and possible storms will continue in Victoria, Tasmania and southern New South Wales on Wednesday and Thursday possibly heavy in Tasmania.

Rainfall totals of 25 to 50 mm are likely across south-east South Australia, eastern and southern NSW much of Victoria and Tasmania. Total rainfall of 50 to 100 mm is more likely along the Victorian ranges, NSW south coast and much of Tasmania. Isolated higher totals in excess of 100 mm are possible.

This rain will likely produce localised flash flooding, and as rainfall accumulations grow, riverine flooding will increase on many rivers, which will cause renewed or prolonged rises for already-flooded catchments.
