- Weather Situation
- Ex-Tropical Cyclone Tam has transitioned into a deep Tasman low pressure system, driving fresh southerly winds and large powerful waves to the coastal waters. Winds should shift north to northwesterly during the weekend as the low continues to move towards New Zealand while a cold front and its associated trough approaches to the coast from the west. These systems will cross the coastal waters on Monday, and a low pressure system is forecast to develop off the south coast in its wake. Winds and surf will increase from Tuesday as the low deepens and heads northeastwards.
