Forecasts

Monday 15 December to Sunday 22 December This week is shaping up as a classic pre Christmas contrast across Australia.Heat dominates the north and interior, while the south experiences very strong winds, rough seas and sharp temperature swings. As we move toward 18 to 24 December, the atmosphere becomes more energetic, increasing the risk of severe thunderstorms and localised heavy rain, especially inland and across parts of the east.

Today’s update covers the developing weather signals across Australia as we transition from the current dry and heating phase into the next High Energy Period and tropical cyclone genesis window due 8 to 12 December.

The current High Energy Period (19–24 November) reaches its peak today, coinciding precisely with the maximum intensity of Severe Tropical Cyclone Fina. The system is now beginning to weaken and will continue tracking southwest towards the North Kimberley coast and Mitchell Plateau from 25 November onwards.

A highly dynamic national pattern is unfolding, driven by Tropical Cyclone Fina across the northern Top End, widespread severe heat across inland Australia, and increasing thunderstorm activity along the eastern seaboard.

Tropical Cyclone Fina Update – Alignment with the 19–24 November High-Energy Period

High Energy Period 19-24th Intensifies: Tropical Low 02U and the Escalation of National Severe Weather
