Cool, wet and windy conditions are expected over southeastern Australia for the end of the week and the weekend.
A deep low pressure system south of the bay will push a series of cold fronts and troughs across the southeast over the next few days.
The first front crosses Victoria, New South Wales and Tasmania today, bringing a band of rain and thunderstorms that are expected to intensify on the western slopes of the Great Dividing Range this afternoon.
Severe thunderstorms may develop over NSW and southern Queensland today, and can produce damaging winds, large hail and/or heavy rain.
Today’s front and rain will gradually move away into the Tasman Sea tomorrow, but the reprieve will be short-lived in parts of the southeast as a follow-on front, bringing gusty showers and thunderstorms in southern South Australia today, moving through Victoria, Tasmania and southern New South Wales tomorrow.
The cold and wet weather will continue over Vic, Tas, southern New South Wales and southeastern SA on Saturday and Sunday.
Maximum temperatures are expected to be 4-8°C lower than average over the weekend and the snow level will drop to around 1100-1200 metres.
Rainfall over the next few days is expected to cause further river surges, particularly in parts of New South Wales, northeast Victoria and northeast Tasmania, and flood watches have been issued . There are numerous ongoing flood warnings for the interior of New South Wales, southern Queensland and northern Victoria
Severe thunderstorms are a risk today, particularly over inland parts of NSW and southern Qld. Warnings may be issued for severe storms producing damaging winds, large hail and/or heavy rains that can lead to flash flooding.
Windy conditions are also expected to develop but are currently expected to remain below warning levels. The Bureau will continuously monitor the conditions and warnings will be issued if necessary.
Note that saturated soil can lead to wind damage even below warning thresholds.
This weather system is also likely to cause large waves and abnormally high tides along the southern coast of South Australia and south-west Victoria and can cause hazardous conditions for some coastal activities.
Communities are encouraged to keep up to date with the latest forecasts and warnings on the Bureau’s website or the BOM weather app.
