The M1 has reopened after being cut by floodwaters for six hours today while theme parks remain underwater after ‘life-threatening’ flash flooding hit parts of southeast Queensland during a wild 300mm deluge.
Though the wet and stormy conditions are not over as at 10.30pm on Saturday residents in parts of the Sunshine Coast, Wide Bay and Burnett regions are being told to prepare for thunderstorms with potentially heavy rainfall that may lead to flash flooding.
A severe thunderstorm warning was issued by the Bureau of Meteorology at 9.56pm as a band of thunderstorms develop over the southeast coast.
Areas that may be impacted by the storm include Maroochydore, Gympie, Noosa Heads, Maryborough, Nambour and Rainbow Beach.
Tewantin, near Noosa, has recorded 7.2mm of rainfall since 9.30pm.
The severe storm warning - which was issued during intense rainfall from the mega cell that extended from the Sunshine Coast down to the Gold Coast - was cancelled about 7am Saturday after an overnight downpour caused flash flooding on major roads.

The M1 reopened six hours later - just before midday - but gridlock will take a while to clear after motorists were diverted off the M1 onto service roads near the Movie World exit at Oxenford.

Earlier, drivers reported it took more than one hour to make the usual 5-minute trip from Smith Street to the Oxenford exit.
Exit 49 at Pimpama was also closed after several motorists travelled the wrong way up the southbound on ramp to escape the gridlock.
At the height of the downpour, traffic cameras showed lines of cars pulled over on the side of the road, unable to get through floodwaters.
In other parts of the M1 between Brisbane and the Gold Coast, the rainfall was so heavy motorists were forced to slow to half-speed, as visibility and flash flooding caused dramas.
Motorists are advised to avoid the area at all costs with severe flooding also forcing Gold Coast theme parks Dreamworld, WhiteWater World, Movie World and Wet n Wild to close today.

A ute was swept away at Country Paradise Parklands on Beaudesert Nerang Road, Nerang and flood waters are to the rooves of cars on Ferry Road, Southport.
At Southport, the normally quiet Keebra Park was flooded with water, turning it into a river-like raging torrent.
“Our park has turned into a river, this is really scary,” one resident said.
Earlier, the Bureau of Meteorology warned that very dangerous thunderstorms were detected on the weather radar near Hope Island, South Stradbroke Island and Tallebudgera.
These thunderstorms were slow moving and hit the wide region from Coolangatta to Nerang, Numinbah Valley and Mount Tamborine..
