Overview
- Rain reached Adelaide with the first band already spreading up to 20 millimetres across South Australia by sunset, according to the ABC.
- The Bureau of Meteorology forecasts about 20 mm for the city followed by 15 mm, with smaller falls after that, and some models point to totals near 40 mm for the event.
- Forecasters say the inland trough is drawing tropical moisture south and a blocking high over the Tasman Sea is slowing the system, which keeps it in place longer.
- The rain is arriving from the north and northeast, which is unusual for Adelaide and helps explain why the wet spell is expected to linger into mid-week.
- On the east coast, warm Tasman Sea eddies 2–4°C above average are keeping Sydney mild and showery, with highs of about 22–24°C reported this week.
