But its not unprecedented, is it...Unlike El Nino years, the impacts of La Nina often continue into the warm months. In eastern Australia, the average December-March rainfall during La Niña years is 20% higher than the long-term average, with eight of the ten wettest such periods occurring during La Niña years. This is particularly notable for the east coast, which tends to be less affected by La Niña during the winter months but can experience severe flooding during La Niña summers.The presence of La Niña increases the chance of widespread flooding. Of the 18 La Niña events since 1900 (including multi-year events), 12 have resulted in flooding for some parts of Australia, with the east coast experiencing twice as many severe floods during La Niña years than El Niño years[URL unfurl="true"]http://www.bom.gov.au/climate/updates/articles/a020.shtml[/URL]
