- Weather Situation
- A high pressure system over the Tasman Sea extends a ridge towards the north coast while a trough off the central coast is weakening. Then, another trough looks set to cross the southern and central parts of the coast on Wednesday, bringing a fresh southerly wind change in its wake, before reaching Mid North Coast on Thursday and weakening. This system will be followed by a high pressure system passing to the south, maintaining onshore easterly airstream across the coastal waters through the second half of the week.
