Forecast issued at 5:07 pm CST on Monday 10 December 2018.

Weather Situation

A trough is located near the base of the Top End and extends into the southern Gulf of Carpentaria to ex-Tropical Cyclone Owen over Cape York Peninsula. The system is expected to move west into the Gulf of Carpentaria later tonight or Tuesday and is likely to reintensify into a cyclone on Wednesday. Increasing showers and thunderstorms especially over eastern Top End and Carpentaria District from Tuesday as the system moves closer. Monsoon onset is possible over northeast Top End during the week but is dependent on movement and development of ex-Tropical Cyclone Owen. A prolonged heatwave event across much of the Territory continues, with daytime temperatures exceeding 40 degrees Celsius in some parts. A cooler southerly change will finally bring some relief following the passage of a trough through southern and central districts from Thursday.
