The Northern Territory has enjoyed a fairly dry week with a break in the monsoon, but rain and storms are spreading inland this week in abundance.
A weak monsoon low is currently moving slowly through the Gulf of Carpentaria towards the Northern Territory, after bringing plenty of rain to northern Queensland. This low is unlikely to develop into a tropical cyclone, but as it moves over the NT rain and storms will come with it.
It has been a week since a band of rain spread across central parts of the NT, with only the Top End seeing any showers and storms since then.
From today, rain and storms are beginning to spread into the Roper-McArthur region and eastern parts of Arnhem. On Monday and Tuesday rain will gradually spread further inland before the trough deepens on Wednesday with areas of rain and isolated showers and storms across all inland districts, possibly as far south as Alice Springs and as far east as the central Kimberley.
The heaviest rain this week is likely to be along the coast of the Roper McArthur district, with widespread totals over 150mm. The next heaviest area should be from Roper Valley to just south of Tennant Creek, with widespread totals of 80-150mm and isolated falls over 200mm.
The rain is likely to gradually contract to the east from Thursday, but significant falls will continue in the Roper-McArthur and Barkly districts until the weekend.
