SOUTHERN Victoria can expect the long, dry spell to go even longer.

The Bureau of Meteorology's latest climate outlook, released today, says there is only a 30 to 35 per cent chance of getting above average rainfall in the south during the next three months.

The national outlook for March to May shows a wetter than normal autumn likely for much of South Australia, western NSW, southwest Queensland and western Western Australia.

A drier season is forecast for Tasmania, southern Victoria and southwest WA.

A bureau spokesman said the outlook was predominately a result of warmer than normal waters in the Indian Ocean.

Near normal temperatures in the tropical Pacific Ocean had less of an impact on this forecast, the spokesman said.
