Northern Territory 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.
With a few days to go until the official end to the summer season, it looks like parts of New South Wales could still see the odd drop of rain.
A weak cold front will clip the southern parts of South Australia today and reach Victoria in the afternoon.
Heavy rainfall that caused flooding across southern Western Australia a week ago has filled Perth's river systems with sediment and nutrients, as well as potentially harmful bacteria.
