Parts of the south-east could be in for a battering today with damaging wind gusts, intense rainfall and life-threatening flash flooding possible across the region.
A Severe Weather Warning remains in place from Hervey Bay and Fraser Island, across the Sunshine Coast, as well as for coastal areas and islands down to the border.
Felim Hanniffy from the Bureau of Meteorology says there is some uncertainty surrounding how a trough, containing a developing low, will evolve over the next 24 hours.
"The low itself has remained east of Fraser Island overnight, so that has spared the coastline the heaviest rainfall totals," he says.
Lady Elliot Island, near where the system is currently hovering, has recorded the heaviest falls overnight, with 180mm falling there.
The senior forecaster says coastal fringes of the Sunshine Coast could be in the firing line on Easter Monday, if the system does drift to the west.
"If that low was to push back closer to the coast it would put the Noosa and the Sunshine Coast itself, Maroochydore and that area, at risk of localised very heavy falls, but a lot hinges on where that system goes.
"If it remains offshore then that risk diminishes.
"If it moves closer you could see some very intense falls, localised falls of 200mm or in excess of that, if that system was to move onshore and you get storm activity."
Dangerous surf conditions for beach goers
As the system develops, it is also expected bring some strong and potentially gale-force winds to our coastal waters, causing dangerous surf conditions for swimmers and boaties.
A Hazardous Surf Warning is in place from the Capricornia Coast, Fraser Island Coast, Sunshine Coast Waters and Gold Coast Waters.
Blues skies to return from tomorrow
The weather is set to improve after the Easter long weekend draws to a close.
Mr Hanniffy says things are looking up from tomorrow.
"There is a reprieve if you look towards the middle of the week, onwards.
"It's generally much brighter and temperatures are warming up as well."
