Spencer Gulf Coastal Waters Forecast

No warnings for South Australia

Forecast issued at 3:50 pm CDT on Tuesday 22 October 2019.

Weather Situation

A high pressure system east of Bass Strait will move slowly eastwards to be centred over the northern Tasman Sea on Wednesday. A slow moving trough of low pressure will be near the western border until early Thursday, ahead of a vigorous cold front which will move across the western coasts during Thursday, reaching Gulf waters late afternoon or evening and the South East coasts late evening. A colder, fresh to strong and gusty southwesterly airstream will follow the front, and persist on Friday, but ease over western coasts later as a ridge of high pressure develops over the Bight. Conditions will ease further on Saturday as a high pressure system develops to the west of the Bight.
