BOM - It's Official!

The Bureau of Meteorology announced today that Australia is in an La Nina event.

Generally speaking La Nina means a wetter than average weather, cooler days and warmer nights, more severe cyclones.

Overall, models do not currently anticipate this event will be as strong as the La Niña of 2010–12, which was one of the four strongest La Niñas on record. The strength of La Niña impacts on Australia are often related to the strength of the event.

Central and eastern tropical Pacific Ocean sea surface temperatures exceed La Niña thresholds (0.8 °C below average) and atmospheric indicators, including the Southern Oscillation Index (SOI), trade winds and cloud, are also at La Niña levels.
