A storm cell moving north from New South Wales hit Brisbane before 4pm on Sunday and was continuing to move north-west in the evening after dumping heavy rain in Brisbane's east.

The Bureau of Meteorology described the storm as "very dangerous" and reported Carindale, in Brisbane's east, received 68mm of rain in just 30 minutes up until 4.45pm on Sunday afternoon.

The Department of Transport and Main Roads reported flash flooding in several Brisbane suburbs. Roads affected included Vulture Street in Woollongabba, Stanley Road in Carina and Moggill Road in Indooroopilly.

Energex said more than 1400 homes in the Brisbane City area were left without power on Sunday evening following the storm.

North-west of Brisbane, Mount Glorious received 60mm of rain in a 30-minute burst before 6pm. The storm then moved on to Esk at about 7pm before heading south again towards Ipswich.

A second severe storm cell near Kingaroy, 220 kilometres north-west of Brisbane, was also dumping heavy rain during Sunday afternoon.

BoM forecaster Adam Woods said the Burnett region had recorded more than 70 millimetres of rain since 9am thanks to the storm cell to the north of Brisbane.

Mr Woods said he expected south-east Queensland rainfall figures to have reached 100 millimetres by Monday morning in the wake of the two severe storms.

The wet weather brings a welcomed decrease in top temperatures across the south-east after maximums in the late 30s to early 40s on Saturday.

Earlier Caloundra residents were stunned by a land spout briefly appearing over the Sunshine Coast suburb.

Appearing like a tornado, a funnel of moist air formed over inland Caloundra and images were posted on social media.

The Bureau of Meteorology said the unusual formation was most likely to be a water spout crossing over land than a tornado.
