The third wild storm to his South-East Queensland this week cut power to 45,000 homes and businesses across the region.

While rainfalls were limited to 31mm in Brisbane's inner-city suburbs, wind gusts reaching 72kmh blasted the riverside.

In the CBD, a fallen tree blocked the southbound lane of busy North Quay, and a tree fell on a car on Ann Street. No one was injured.

Power lines fell across the road on Heussler Terrace at Milton and a pedestrian was hit by a car on Main Street, Kangaroo Point.

A large area of the state was battered by a band of storms that swept in from the west, reaching Brisbane about 6.30pm.

According to the Bureau of Meteorology, the storms developed north of Granite Belt yesterday afternoon, before steering east.

The storm cells "lined up like they were on a score line", forecaster Gordon Banks said.

"The first line of storms hit and then the second line hit within an hour," Mr Banks said.

The strongest winds, reaching 100kmh were recorded at Toowoomba overnight.

Wind speeds topped 85kmh at Coolangatta about 6.30pm, while winds of 74kmh were recorded at Brisbane Airport 45 minutes later. Offshore winds swirled Moreton Bay at 133kmh.

Ipswich residents, who awoke to rising flood waters yesterday morning, were last night spared from a second torrential downpour, with 6mm of rain at Tallegalla and 13mm at Gatton.

In Brisbane, Mt Gravatt received 17mm, while Burbank received 36mm and 15mm fell at Slacks Creek, with Toowong and Red Hill receiving 23mm.

Energex said power had been cut to 45,000 homes and businesses across Brisbane, Logan, the Gold Coast and the Sunshine Coast.

By 5.30am this morning, only 1500 homes were still without power, mainly on the Gold Coast and in Logan.

Brisbane suburbs devastated by the storms on Sunday and Wednesday, such as Paddington, Red Hill, Ashgrove, Arana Hills and Everton Park, again suffered significant damage including fallen powerlines, trees and branches blown onto powerlines, and water seeping into underground cables.

"While it's been a busy week for Energex crews, strict fatigue management practices means there are dozens of crews rested and ready to work throughout the night," an Energex spokesman said.

"Energex crews will work as quickly and safely as possible to restore power and thank customers in advance for their patience."

Queensland Premier Anna Bligh said the community was feeling the pressure of so many severe storms in such a short time.

"I have to say, after being out on the ground, people are coping very well, although I'm certainly starting to see some very tired folk and we hope to give a decent rest as soon as possible," she said.

Some of the state's best farmland has also been affected, although the deluge would have a long-lasting benefits for farmers, Ms Bligh said.

"I saw creeks that have been dry for 12 years that are now flowing strong and every dam I saw, every rural dam, was full. So that sort of rain would be good in the long term," she said.

"Here in the metropolitan area, 4000 homes have been damaged. More than 600 of them have had tarps put on their roofs.

"We have now seen just on 10,000 insurance claims, amounting to $95 million.

"... It's now becoming very disspiriting and demoralising. Some of these homes have been hit more than once, and people just feel they can't get on top of it.

"Many of them have lost some of their most precious treasures. The water damage, even from a small hole in the roof, when every single night we've had the heaviest rain, so if you got a small hole in your roof on Sunday night you might have now tarped it once or twice and seen extraordinary water damage come through that part of your house."

While the storms had added water to the state's dams, the storages still weren't at 50 per cent capacity, not enough to warrant relaxation of water restrictions.

"So they are still half empty and we've still a very large, growing population.

"The recycled water pipeline is providing water to run our power stations, and there is supplementary water available in March from that pipeline."

Therefore, the government would not delay plans to put recycled water into the drinking water supply serving south-east Queensland.

"We have all the best scientific advice that this is perfectly safe. I've drunk it myself, I've drunk 100 per cent water out of the pipeline," Ms Bligh said.
