By far the wettest part of the country this Christmas period, Brisbane adds to the wettest month in over a decade. From Christmas Eve to Boxing Day, Brisbane received 105mm with 60 of that falling on Boxing Day. With just a few days left in the month this takes their monthly total to nearly 4 times the average. The airport picked up 120mm taking the total this month to 449mm. So far this is the wettest month in 14 years. On Boxing Day the Gold Coast was soaked with a widespread 80 to 120mm falling to 9am on Monday. The Gold Coast Seaway collected 112mm making it the wettest December day in at least 16 years. A low pressure trough is the main reason for all this rainfall, drawing in huge amounts of moisture from the tropics and the Coral Sea. Helped along by ex-tropical cyclone Tasha which fed extra moisture into the trough. On Monday up to another 100mm is expected for the southeast and Brisbane just adding to any local flooding. By midweek, the trough is expected to have moved northward allowing rain to ease from the southeast, but bring more rain to the central coast. By New Years Eve conditions are looking dry for the southeast and just a few showers on the central coast.
