The Bureau of Meteorology’s latest El-Nino Southern Oscillation outlook continues to project a 70% chance for La Nina.

The alert means the likelihood of a La Nina event occurring in upcoming months, as a result of cooling sea surface temperatures in the Pacific, is three times the usual.

It would be the third La Nina in a row, resulting in likely increased rainfall in Northern and Eastern Australia throughout spring and summer.

The outlook also says a negative Indian Ocean Dipole will continue into spring, typically causing above-average seasonal rainfall.
