Wet weather caused by La Niña could end by winter, forecasts show

The La Niña weather event which has caused a wet summer across Australia may soon come to an end according to the latest models by the nation’s weather forecaster.

The Bureau of Meteorology (BoM) said there has been little change to the conditions over the past few weeks but waters are warming to neutral El Niño – Southern Oscillation (ENSO) levels.

ENSO has little influence on rainfall meaning Australia could soon see an end to the unprecedented downpours by early winter.

“Most climate models surveyed by the Bureau indicate a return to neutral El Niño–Southern Oscillation (ENSO) by the early southern hemisphere winter,” the bureau said.

“Only one of seven models continues La Niña conditions through the southern winter.”

La Niña, which is Spanish for The Girl, is a complex weather pattern that pushes warm water towards the western side of the Pacific.

“La Niña events typically begin in the Southern Hemisphere’s winter or spring, peak in spring and summer and break down in autumn,” Weatherzone’s Ben Domensino said.

“This year’s La Niña is remaining unusually well-established into the back end of autumn.”

For the second time in weeks outback Queensland is bracing for a soaking. Trish Sloan, an employee at the Australian Age of Dinosaurs Museum, was on site as water  pouring down a rocky outcrop, forming a waterfall.  The Britton Way causeway can be seen in the background.

The La Niña conditions that the nation is experiencing now started in November when it formed over the Pacific Ocean.

It is the second year in a row Australia has experienced the weather event.
