Weather Situation
A high pressure system in the Indian Ocean extends a ridge over southern coastal waters, and brings a south to southeasterly flow to much of the western coast. A weak front will brush the south coast on Friday, before the high pressure system starts to move eastwards through the Bight over the weekend, a south to southeasterly flow remaining about western coastal waters throughout.
