Written by Josh Agnew on June 22, 2020
As SEVERE WEATHER continues to lash many parts of the state, the Bureau of Meteorology has issued a minor flood warning for the Huon River.
Around 10–30 mm of rain is expected in the southeast, Upper Derwent Valley and lower east of the state today, and up to 60 mm possible in elevated areas.
Tomorrow will see further rainfall with 15–30 mm forecast for eastern, southern and central areas, and up to 60 mm possible in elevated areas.
Widespread rain began in southern and eastern areas on Sunday with some of the highest totals recorded from 9am Sunday to 9am Monday including:
o Kunanyi/Mount Wellington & Crabtree – 45.6 mm
o Nugent – 45 mm
o Wattle Hill – 38 mm
o Little Swanport (Lisdillon Far) – 37 mm
o Southport – 36.2 mm.
Strong east to southeasterly winds will also be a feature today and Tuesday for the lower east and south east of the state, with gusts of 70–80 km/h possible at times from late this afternoon and evening.
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.
