UPDATE: Flood warnings issued for Fraser Coast river systems
UPDATE 5.45PM: THE Maryborough swift water rescue team has been sent to help four people evacuate a home in Howard, as flood warnings have been issued for the area.
The emergency services team was called to the James St home just after 3pm.
It is believed two children and two adults needed help fleeing rising creek waters that were coming up to the back of the house.
As the last of the heavy rainfall from ex-tropical cyclone Debbie fell over the Fraser Coast just after 3pm, the attention of the local disaster management group members turns to the potential flooding, strong winds and surging seas which may lay ahead.
The Bureau of Meteorology said moderate flooding was likely along the Burrum and Cherwell Rivers overnight.
The Burrum River at Howard is likely to exceed the minor flood level Thursday evening, and the river level is likely to peak between 6.5 and 7 metres between Thursday night and Friday morning.
The Cherwell River at Pacific Haven is likely to exceed the minor flood level Thursday evening and the moderate flood level overnight and is likely to peak near 3.4 metres early Friday morning.
Following a 3pm local disaster management group meeting, Acting Inspector Dave Briese said people needed to be aware of the prevalence of flash flooding.
"After driving around the CBD…the big message would have to be if it's flooded, forget it," Acting Insp Briese said.
"Also we're still waiting on the river catchment situation [south of Maryborough] to actualise."
Local Disaster Management Group acting chairman Stuart Taylor said the group was still on "stand up" status, as there was still damaging winds and dangerous oceans to come.
"People still need to exercise caution," Cr Taylor said.
Properties in Pacific Haven are expected to be affected by a 3.5m flood of the Cherwell river.
Cr Taylor said the disaster management group would be monitoring the Cherwell's levels throughout the night, but the moderate flood was not expected to impact on homes.
"The modelling at this stage doesn't indicate that," he said.
"It's moderate, but there may be some road disruptions."
A minor flood warning has been issued for the Burrum River, but no warning has been issued for the Mary River.
Cr Taylor said over the next few days, the disaster management group would be assessing any environmental, economic, social or structural damage caused by the wild weather.
"It's really minimal environmental damage at this stage," he said.
FRASER Coast residents are urged to be cautious of flash flooding on Thursday afternoon.
With rain expected to dump anywhere between 100-300mm today, roads are expected to be cut off with little to no notice.
The Local Disaster Management Group have asked residents to stay off the roads this afternoon as the deluge continues.
Local disaster management acting chairman Stuart Taylor told the Chronicle the two major significant issues that will face the region include the storm surge and road flooding.
"We expect roads to be closed with little to no warning," he said.
"Flash flooding in these weather events is a reality.
"We ask people to exercise extreme caution on the roads today."
A STORM surge of half a metre is projected to potentially inundate areas of Hervey Bay with winds forecast to hit 125kmh about 1pm.
Along with the gale force winds and the surge, water is estimated to reach possibly reach 4.2 metres which will affect low-lying areas.
It has prompted the Local Disaster Management Group to set up evacuation and respite centres in Maryborough and Hervey Bay for residents affected by ex-Tropical Cyclone Debbie.
Yet to be staffed until later today but already set up at the Maryborough Showgrounds and the Hervey Bay PCYC, residents are urged to use them as a last resort if they are unable to stay with family or friends.
Local disaster management acting chairman Stuart Taylor said currently they won't be needed but will be available later for affected residents.
"These are safe spaces for residents who feel the need to move away from the storm surge area," he said.
All boat ramp, beaches and the Urangan Pier have been closed from the public as waves lash the coastline.
EARLIER: WITH up to 300mm of rain predicted to fall in the Fraser Coast region over the next 24 hours, the Local Disaster Management Group has moved to "stand up" status.
Local disaster management acting chairman Stuart Taylor said crews had set up a coordination centre in Maryborough and were collecting data as preparation for today's forecast rain.
"When we look at the rain forecast, on the MetEye data's chances of rain over the next three hours, if we look at the 10am data it shows how much rain could be caught in a three hour period, we're in dark blue, we're going to get anywhere between 90-100mm of rain in the three hour period," Cr Taylor said.
"And then at 1pm, there's a significant level of rain [forecast], [MetEye] estimates for today show between 100 and 300mm of rain in this 24 hour period."
Cr Taylor said the predicted rain was "a short-lived cell" and there was "not a lot of rain behind it".
He said after the rain had passed, the team would be able to make an assessment about river levels, and prepare for any downstream impact on Howard, Pacific Haven and Maryborough.
