At 4pm AEST Tuesday, Tropical Cyclone Linda (Category 1) with central pressure 994 hPa was located in the Coral Sea near latitude 19.3 south longitude 159.5 east, which is about 880 km northeast of Sandy Cape and 1100 km east of Mackay.
"The system will most likely shift to the southwest during today before taking on a more southerly track on Thursday and is expected to remain offshore of the southern Queensland coast".
"On Wednesday, it'll start to move down the coast, bringing unsafe surf conditions, large swells, possible high tides in the morning and strong to even gale-force winds", meteorologist Grace Legge, Bureau of Meteorology, said.
Tropical Cyclone Linda is expected to lose its puff today as it heads towards the Queensland coast, already showing signs of weakening over the Coral Sea.
On Wednesday, it is predicted TC Linda will transition into an intense subtropical low as conditions become unfavourable.
Southeast Queensland beaches could be pounded with four-metre waves in coming days as a tropical low sweeps along the coast.
Big seas are expected from Wide Bay down to the NSW border from Wednesday, while abnormally high tides could impact coastal areas from Thursday. A severe weather warning iscurrent for these conditions.
It comes as the Bureau of Meteorology announced Queensland's La Nina period had officially ended.
The weather bureau said the short-lived La Nina had "relatively little effect on Australian rainfall patterns over the 2017-18 summer".
