No warnings for the Northern Territory
Forecast issued at 4:30 pm CST on Monday 18 January 2021.
Weather Situation
A monsoon trough extends along the southern Arafura Sea to a weak tropical low located near the Cobourg Peninsula. The tropical low is expected to continue moving westwards for the remainder of today, then westwards across the Timor Sea during Tuesday. The tropical low is not expected to develop significantly during this period but is expected to bring rain and heavy falls to the northern Top End. A high located to the south of the Bight will maintain a ridge across central Australia until the middle of the week, resulting in clear skies and a developing heatwave. A trough located near the base of the Top End will shift southwards over the next few days as the ridge weakens, dragging isolated shower and thunderstorm activity southwards across the Territory.
