Issued: Friday 6pm 02 September 2022
A trough is moving across eastern Australia bringing widespread rain, thunderstorms, wind and large surf.
Wet and windy conditions are expected across the northern half of the New South Wales coast from late Friday as a low-pressure system develops with the trough near the southern Queensland and northern NSW coast.
This low brings the potential for gusty winds, increased rain (most likely along Mid North Coast), localised flash flooding and large waves to the northern half of the NSW coast. Similar conditions are expected at Lord Howe Island on Saturday, and on Norfolk Island on Sunday and Monday as the low moves eastwards across the Tasman.
A Hazardous Surf Warning is current for Byron Bay, Coffs Harbour, Macquarie and Hunter Coasts with surf and swell conditions expected to be hazardous for coastal activities such as rock fishing, boating, and swimming. Hazardous surf conditions are expected to continue into next week and may extend to southern Qld coasts later in the weekend.
Minor to Moderate Flood Warnings are current for a number of river catchments in inland NSW and Vic, as multiple flood peaks move downstream. The next rain-bearing system for these catchments is forecast to arrive mid to late next week. This brings the potential for further flooding as catchments are saturated and dams are full or near capacity. People are advised to monitor for regular updates on the BoM website or app.
Flood watches have also been issued for several river catchments around the Mid North Coast of NSW, with minor flooding possible from Saturday depending on the location of the heaviest rainfall.
Rain is extending across southern and eastern Qld today, diminishing to the south-east on Saturday and clearing offshore later.
Thunderstorms are occurring around the central and northern interior of Qld today, with some storms producing damaging winds, large hail, and heavy rainfall. Communities are encouraged to monitor for Severe Thunderstorm Warnings. Further thunderstorms may develop about the Wide Bay and Burnett coast tomorrow morning but are less likely to produce severe weather.
The low-pressure system will bring increasing winds and a Severe Weather Warning for damaging winds is possible for the northern NSW coast and southern border ranges of Qld on Saturday night and Sunday.
The low is expected to move quickly off the coast on Sunday, with rainfall and winds expected to ease in along the NSW coast late Sunday or early Monday and in Qld late Saturday.
Communities are advised to stay up to date with the latest forecasts and warnings via the Bureau’s website and BOM Weather app and follow the advice of emergency services.
