After a dry summer, Australia is due for heavy rain and possible supercell storms.

Superstorms expected to hit across the country

Two major highways are cut and theme parks are flooded after ‘life-threatening’ flash flooding hit parts of southeast Queensland causing havoc.

A super cell has dumped up to 145mm of rain in just two hours.

A severe storm warning - which was issued after intense rainfall from the mega cell which extended from the Sunshine Coast down to the Gold Coast - was cancelled about 7am after an overnight 300mm+ deluge caused flash flooding on major roads.

The Cunningham Highway between Tarome and Maryvale and the M1 both directions at Helensvale have both been closed due to flooding. The Cunningham Highway is expected to be cut for several hours while the super cell passes.

On the M1 at Helensvale, traffic cameras show lines of cars pulled over on the side of the road, unable to get through floodwaters.

Earlier on the M1, the rainfall was so heavy that motorists between Brisbane and the Gold Coast were forced to slow to half-speed, as visibility and flash flooding caused dramas.

The deluge has hit the Gold Coast the hardest with 145mm of rain recorded at Monterey Keys in just two hours and 86mm at Coomera Shores in one hour.

According to the weather bureau, parts of the Gold Coast has recorded 300mm overnight - triple the monthly rainfall.

Police were called to 52 incidents and two swift water rescues were performed.

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..
