Rain From North To South
Rain has fallen across much of the NT from a combination of a cloud band extending across central Australia and thunderstorms and showers in the Top End.
By 9am yesterday morning:
Steady overnight rain in the south resulted in:
- 36mm at The Garden northeast of Alice Springs with similar falls nearby of 35mm at Arltunga and 34.4mm at Gemtree Park
- 18.2mm at Undoolya, just east of Alice Springs town
- 13mm at Alice Springs Desert Park
Late night thunderstorms and early morning showers in the Top End dropped:
- 49.4mm at Bradshaw Training Area, southwest of Katherine
- 35mm at Darwin airport
- 22mm at Port Keats in Wadeye
- 10mm at Tindal (Katherine)
Along with the rain in the south came a swift chill. Alice Springs dropped to 13°C on Monday after reaching a peak of 37.5°C on Saturday. Similarly, Uluru fell to 14°C on Monday, following a high of 39.3°C on Saturday.
Flooding is possible in central parts of the NT today with a flood watch current for the MacDonnell Ranges and Simpson Desert. Heavy falls may lead to significant stream rises. Check your warnings here.
The rainband over central Australia is expected to peak in strength today and drop another 10-40mm of rain around the Simpson district with heaviest falls forecast to be east of Alice Springs before weakening and clearing east from the NT tomorrow.
As the cloud band moves east sunny conditions will return to the south on Thursday, with temperatures forecast to slowly inch up from low 20°Cs on Thursday to high 20°Cs and low 30°Cs by the weekend.
The forecast for Darwin is for more showers and thunderstorms today through to Friday, with only a slight chance of rain Saturday although thunderstorms are still likely and a clear and sticky Sunday and Monday. A maximum of 35°C is forecast on Saturday and Sunday.
More broadly across the Top End thunderstorms and rain are expected today and tomorrow. By Thursday thunderstorms and rain are expected to contract to the western Top End and narrow their footprint even more on Friday to the Daly district. Hotter temperatures in the high 30°Cs will creep back in from Friday across inland areas.
