Qld beaches face battering, up to 250mm rain expected
BEACHES between the Gold Coast and Fraser Island could face significant erosion as heavy rainfall, high tides and strong winds combine to buffet them.
In an advice released on Friday morning, the Bureau of Meteorology said damaging winds, with peak gusts of around 90km/h, are possible near coastal areas and about the Scenic Rim as the surface trough or low develops on Saturday.
"The trough or low will also generate large swells as it slips southwards during Saturday, with dangerous surf conditions and significant beach erosion developing about exposed beaches between Fraser Island and the Gold Coast during Saturday, contracting southwards out of the Fraser Coast waters by Sunday.
"Water levels on the high tide are likely to exceed the highest tide of the year about exposed beaches between Fraser Island and the Gold coast on Saturday and Sunday, particularly on the high tide Saturday night and Sunday morning.''
Heavy falls are expected on Friday and early Saturday over parts of the central and southern interior though are more likely to be associated with thunderstorms.
A Flood Watch is current for southeast Queensland from Fraser Island to the NSW-QLD border extending inland to include the Upper Condamine, Dumaresq and Macintyre Rivers.
Locations which may be affected include Hervey Bay, Warwick, Gold Coast, Toowoomba, Brisbane, Maroochydore, Gympie, Stanthorpe and Caboolture.
The bureau said a strong upper trough will move east into the southern interior of Queensland on Friday, shifting into southeast Queensland on Saturday, before moving off the southern coast during Sunday.
A surface trough will deepen near the Capricornia or Wide Bay coast during Saturday.
A low pressure system could develop, slipping southwards over southern Queensland waters during Saturday and most likely moving offshore or into New South Wales late Saturday or early Sunday.
Heavy rain, which may lead to flash flooding, could occur in areas southeast of about Hervey Bay to Toowoomba to Warwick on Saturday.
24 hour totals of 30 to 150mm are likely over inland parts, with falls in excess of 250mm possible nearer to the coast and ranges.
The heavy rain areas should contract southeast during Saturday, gradually clearing the Gold Coast late Saturday night or very early Sunday.
