A Sheep Graziers Warning is current for the Midlands, East Coast and SouthEast today and Tuesday due to rain, winds and cool temperatures.

The wet and windy weather is due to a low near Tasmania’s northwest coast, which will gradually move away on Tuesday and see conditions easing on Wednesday.

Widespread rain will begin over southern and eastern Tasmania on Sunday night and will continue throughout Monday and Tuesday, before easing on Wednesday.

Over the next 3 days widespread rainfall totals of 30-70 mm are forecast for the south and east, with possible higher totals exceeding 100 mm in isolated and elevated areas. The heaviest rain for the southeast is expected during Monday.

A flood watch is now current for North and North East, Huon, Derwent andSouth East catchments. River rises are expected with the forecast rainfall and minor to moderate flooding is possible at some locations from Monday afternoon.

East to southeasterly winds will become strong and gusty during Monday and Tuesday for southern and eastern Tasmania with wind gusts of up to 70 – 80km/h possible at times.

The widespread rain and gusty winds will be caused by a low pressure system near Tasmania’s northwest coast on Monday and then gradually moving away on Tuesday.

Small changes in the position of a low pressure system can lead to large changes in rainfall and winds. Uncertainty due to low pressure system movement may lead to changes in the forecast rainfall over the next few days.
