Tasmania 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.
A band of rain sweeping over Victoria may cause flooding in the state's north and northeast in the next 24 hours.
Parts of northern Tasmania are having one of the wettest winters on record, but it isn't over yet.
The final rainband of the season is sweeping across South Australia today, but the heaviest rain is going to fall where it shouldn't.
