New South Wales/ACT 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.
About 9,000 properties remain without power in Perth and Western Australia's south-west as conditions ease across the state after damaging winds brought down trees and debris.
The South Australian towns of Virginia and Port Wakefield are under threat from floodwaters as the Gawler and Wakefield rivers burst their banks, with warnings more rain is on the way.
An evacuation order has been issued for low-lying areas of Condobolin in the central west of New South Wales, as flood peaks in the Lachlan River move downstream.
