- Weather Situation
- A tropical low pressure system centred over the southeast of the NT extends a trough into the northeast of SA. This low is expected to remain near stationary until Friday, after which it is expected to move southwards over the weekend. A high pressure ridge over waters to the south of SA will move into the Tasman Sea later in the week, pushing the trough back west over central SA this weekend.
