View the current warnings for Tasmania

Forecast issued at 4:05 pm EST on Monday 31 August 2015.

Weather Situation

A broad area of low pressure persists over the Tasman Sea, cradled by a high to the south which extends a ridge over Tasmania. Another low is expected to intensify over the Bight on Tuesday, with a series of cold fronts well to the south. On Wednesday the ridge over Tasmania will weaken while the low moves near Adelaide, then over New South Wales, and a cold front crosses Tasmania overnight. A southerly stream will develop in its wake early Thursday, then ease as a high tracks over the Bight. A warm front is then expected to cross early Friday, while the high moves over Victoria.
