Models predict La Niña event will persist into first quarter of
2011

The national rainfall outlook for summer (December-February)
favours wetter than normal conditions in southeast Queensland, eastern NSW,
northern NT and most of WA. Drier conditions are favoured in parts of Victoria,
South Australia and Tasmania.

The pattern of seasonal rainfall odds across Australia is a result of warm
conditions in the Indian Ocean, as well as cool conditions in the equatorial
Pacific Ocean associated with the current La Niña.

La Niña conditions continue to dominate across the tropical
Pacific. Long-range models surveyed by the Bureau suggest that this La Niña
event will persist through the southern hemisphere summer.

La Niña periods are generally associated with above normal rainfall during the
second half of the year across large parts of Australia, most notably eastern
and northern regions. The 2010 event has contributed to Australia's wettest
spring on record.
