Weather Situation
A slow-moving high pressure system over the Tasman Sea extends a ridge over eastern SA. A trough of low pressure over WA is expected to move into western SA later Sunday and over southeastern parts later Monday, while a weakening cold front crosses the Bight. The trough lingers in the east through the middle of the week as a weak high pressure system forms in the Bight.
