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.
Evacuation centres are designed to be a safe place to wait out a cyclone â?? not be a home away from home.

More than 25,000 people need to move from low-lying areas in Mackay by midnight, with fears incoming Tropical Cyclone Debbie could cause inundation of up to 2.5 metres above the high tide level.
