The line of severe thunderstorms brought heavy rain to parts of the south-east on Tuesday and caused power outages in the greater Brisbane area.

Firefighters said they received a call just before 8:30pm from a woman inside the Loganholme house, who said it had been struck by lightning and caught fire.

Crews managed to contain the fire and save the property, and no-one was seriously injured.

Community support group the Logan House Fire Support Network said fire crews managed to save the family's Christmas presents.

The family was then taken to emergency accommodation.

"Great response by emergency services to contain the fire," the group posted on Facebook.

"Great work by the officers to save the children's presents, [but there is] still significant damage to the property."

The support group said the fire was a timely reminder to contact triple zero quickly in the case of fire.

Thousands of residents lost power

The Bureau of Meteorology (BOM) said a line of storms formed over the Carnarvon Range and Scenic Rim, and over New South Wales.

A storm cell moving up from NSW weakened but a larger cell followed it and brought heavy rainfall and warnings of flash flooding to the Gold Coast area, Beenleigh and Logan.

The system then moved over Brisbane and on to Redcliffe and Caboolture.

At 7:30pm, the bureau had already recorded 40 millimetres at Beechmont.

More than 1,200 residents in Logan City and more than 1,100 in Morten Bay lost power, according to Energex.

Christmas Day forecast

The BOM said more rain was likely for the south-east today, with Brisbane expected to reach a high of 24 degrees Celsius

The Gold Coast was set to top 23C and 21C was forecast for Toowoomba.

But while the cool weather may make the Christmas roast more bearable for some, the rest of the state was set to swelter.

The central and western parts of Queensland will see temperatures 5C to 8C above their December average.
