Fine weather for flood-ravaged Queensland

Residents in drenched parts of southeast Queensland can expect to see some long periods of sunshine in the coming weeks.

Forecasters say rain in the upper catchment areas for the Somerset and Wivenhoe Dams will be easing over the next couple of days as the low pressure system that has threatened the region for the last few weeks slowly dissipates.

Only a few showers are expected in the state's southeast on Wednesday and through the rest of the week, with sunshine ahead.

"Brisbane can expect some lengthy fine periods ahead once this rain eases," Geoff Doueal, senior forecaster at the Bureau of Meteorology, said on Wednesday morning.

Mr Doueal said a southeasterly change on Thursday would mostly confine showers to the coastal fringe.

This means flood-affected areas like Dalby - which has been cut in half by the Myall Creek - and Gympie, in the Mary River catchment, can also expect rain to ease.

Mr Doueal said most of the rain is now being concentrated in the state's far north, which is experiencing a recurrence of the tropical storms that battered the region before Christmas.

Areas of southwest Queensland - including Birdsville - can also expect rain in the coming week.

Residents in Brisbane and Ipswich are still on high flood alert, however, with rivers expected to peak on either Wednesday or Thursday.
