Almost 29,000 homes across south-east Queensland have lost power due to destructive winds, lightning and heavy rain, Energex says.
Another 10,000 Ergon customers in regional Queensland are also understood to have lost electricity.
Energex, meanwhile, has recorded more than 1,500 lightning strikes across the region, and hail is pummelling Brisbane’s western and southern suburbs.
The Bureau of Meteorology (BOM) on Sunday afternoon issued a severe storm warning for the Ipswich, Logan, Somerset, Scenic Rim, Lockyer Valley, Gold Coast, Redland City and Brisbane City council areas.
Residents in Bundamba, Forest Lake, Wacol, Runcorn and Acacia Ridge have all reported hail.
Energex said more than 6,700 people had lost power in Brisbane, while 10,817 customers in Ipswich and about 9,000 in Redland were affected.
BOM meteorologist Michael Gray said Monday would be a drier day, but Tuesday was likely to bring another burst of wet weather anywhere between Townsville and the New South Wales border.
“There’s an upper low developing over New South Wales, which is going to bring more of those over the next few days,” he said.
