ENSO Outlook: LA NIÑA

We recently shifted our ENSO Outlook to LA NIÑA.
 
This follows a steady cooling of the central to eastern tropical Pacific Ocean since late winter. Waters in this area have now reached La Niña thresholds (0.8 °C below average), and atmospheric indicators, including the Southern Oscillation Index (SOI), trade winds and cloud patterns, are also at La Niña levels.
 
However, this La Niña is likely to be weaker than recent events, far shorter-lived, and not expected to continue far into autumn. So what does that mean for Australia's climate over the coming months, and what actually is La Niña?

After thorough testing with registered users, we added 20 new catchments to the Bureau’s 7-day streamflow forecast service in early December.
 
This service provides streamflow forecasts with a lead time of up to seven days, to help river managers and users with decision-making.
 

With this expansion, the public service will deliver forecasts for 88 catchments and 168 forecast locations across the country.

Overall, in northern Australia for the 2016–17 financial year:

Total water use was about 8% less than the previous year due to wetter conditions.
