Australia Sea Surface Temperature Anomalies
The sea surface temperature anomaly (SSTA) is the difference between the observed SST and the climatological SST. These anomalies are calculated on a weekly basis.
Positive SSTAs are usually correlated with increased regions of convection (cloudiness and rainfall) while negative SSTAs are usually correlated to reduced convection.
SSTAs can be used as an indicator of the phase of global climate fluctuations, such as the El Nino/Southern Oscillation (ENSO).
The data displayed in this map is the weekly average, centred on the date shown.
Severe weather predicted for Tasmania's north and east on Friday has prompted a public warning from emergency services.
Rain and storms could bring flooding to parts of southern and southeast Australia during the next 24 hours.
People in Darwin and other parts of the Top End may be about to get relief from recent hot weather, with the Bureau of Meteorology (BOM) predicting a monsoon trough will start to affect the area within days.
