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.
Tropical Cyclone Debbie is strengthening quickly on its journey to make landfall, likely between Lucinda and Proserpine on Monday or Tuesday.
A cyclone off northern Queensland could intensify to category five by the time it crosses the coast somewhere between Cardwell and Bowen, near Townsville, the Bureau of Meteorology (BOM) has warned.
A tropical low brewing 600 kilometres north-east of the Queensland coast could make landfall somewhere between Cairns and Townsville early next week as a category four cyclone or higher, the Bureau of Meteorology (BOM) says.
