Water users in areas under Amber Alerts are advised to exercise caution.

Weather Forecast: For February, there remains a likely chance the region will experience above average rainfall.

Maximum temperatures are likely to exceed the average across the region, whilst minimum temperatures are very likely (greater than 80% chance) to exceed the average.

Algae Outlook: Based on the forecast, the current risk for algal growth is high due to the recent heatwave, increasing water temperatures and hence creating very favourable conditions for algae growth.
