Damaging winds, and intense rainfall of up to 300mm are predicted to hit the Sunshine Coast region over the next 24 hours with residents urged to stay home if possible.
There was also the possibility of flooding and severe storms which would further impact the region, authorities warned.
As at 8am all roads into Kenilworth were closed and the area was isolated.
The Mary Cairncross Scenic Reserve Rainforest Discovery Centre and Scenic Reserve at Maleny were also closed today
All river catchments, including Maroochy and Mooloolah rivers are likely to have minor to moderate flooding, including at Picnic Point, Maroochydore.
Sunshine Coast Local Disaster Management Group Chair Mayor Mark Jamieson said with the ground already soaked and a significant amount of rainfall, river networks would be at full capacity and dangerous.
There was also a risk shallow rooted trees may fall due to the heavy winds expected across the region.
“So I ask everyone to please be vigilant and stay off the roads whenever possible,” Mr Jamieson said.
“With waterways already swollen, authorities predict more rain will significantly impact areas across the Coast, causing flash flooding.
“I would also ask for the community to stay away from water courses as fast-moving waters can be incredibly treacherous.”
