An 18-year-old has gone missing after playing in a drain near Logan Reserve in southeast Queensland during ex-Cyclone Alfred.
Caleb was last spotted at a residence on Burdekin Rd around 11pm on Sunday, after he has earlier been playing in a drain, before he ventured out again.
Queensland Police said he has not been seen or heard from since.
Caleb is described as white with short brown hair and he was wearing camouflage shorts and no shirt or shoes.
Carers and police are concerned for his welfare as he has a medical condition.
Police and SES resources have been dispatched to the area and a search and rescue operation is underway.
Anyone with information is urged to contact police immediately.
The Logan River, which borders Logan Reserve, is under a major flood watch warning from the Bureau of Meteorology after heavy downpours overnight.
Residents across some highly populated areas have been told to move to higher ground as floodwaters escalate in the wake of ex-tropical cyclone Alfred.
Warnings span across southeast Queensland regions including Brisbane, Logan, Gold Coast and Ipswich as multiple swollen rivers and creeks break their banks, rising towards homes.
Ex-tropical cyclone Alfred has battered the southeast with heavy rainfall with some totals exceeding 400mm.
Major flooding is occurring on the Bremer and Albert Rivers and the Warrell and Laidley Creeks in Queensland while NSW’s Richmond and Clarence Rivers are also breaking their banks.
There were 17 swift water rescues across Queensland on Monday.
Heavy rain and thunderstorms will continue across southeast Queensland on Monday morning but conditions are expected to ease into the afternoon.
‘However with a lot of water to make its way through the river systems, the flooding impacts are likely to continue, certainly into the middle and maybe latter parts of this week,’ Bureau of Meteorology’s Christie Johnson said.
More than 450 schools across Brisbane remain closed on Monday and bus services have been cancelled as roads are inundated by flash flooding.
Hundreds of thousands of homes remain without power but Energex crews are working tirelessly to reconnect the 200,000 properties.
‘They are putting everything to try and reconnect people, and it’s very difficult to get back on your feet without power,’ Premier David Crisafulli told ABC Radio.
In northern NSW, some 1800 people have been isolated by the deluge and other 18,500 have been told they could be isolated.
Over the weekend, some residents were allowed to return to their homes in places such as Lismore as conditions eased but authorities are keenly watching further rainfall.
