The Bureau of Meteorology has again warned of the possibility of an El Nino event in the  next few months.

The latest update has declared a 70% chance of an El Nino developing this summer – triple the normal likelihood.

This means the risk of wildfires and heatwaves is dangerously high this summer, regardless of whether or not an El Nino occurs.

In addition, the bureau has also raised awareness of a positive Indian Ocean Dipole, in which increased convection causes a reduced chance of rain in Australia.
