Damaging winds coming from an “unusual direction” and flooding from heavy rainfall are making their way to Tasmania’s North West region.

The Bureau of Meteorology Tasmania has issued a severe weather warning for damaging winds, expected to arrive on Thursday.

King Island, and areas along the North West and West Coast like Currie, Smithton, Waratah and Rosebery will be impacted by winds averaging 60-70km/h.

The BOM Tasmania website said peak gusts could reach 80-90km/h from Thursday morning into the evening.

“A trough deepening over Victoria today will cause east to north-easterly winds to strengthen for Thursday about northwestern parts of Tasmania,” the BOM website reads.

“These winds are from an unusual direction, and may cause damage to different areas than normal for this wind strength.

“Winds are expected to ease below the warning threshold in the late evening.”

A minor to moderate flood watch is in place from Friday morning amid a forecast for heavy rain and thunderstorms.

“Something to keep an eye on after the winds … is the potential for heavy rain about the northern half of Tasmania Thursday evening continuing into Friday with the potential for some very interesting thunderstorms,” senior meteorologist Luke Johnston said.

“It’s very likely we’ll be issuing another severe weather warning for heavy rainfall about northern Tasmania … for a period covering Thursday evening through to Friday afternoon.”

Between 60-100mm of rainfall is expected in the North West and North East during the 36 hours ending midnight Friday.

More than 150mm could lash the Western Tiers, and more than 120mm could fall in the northeast highlands.

The Central North could see 20-60mm, while the rest of the state can expect 15-35mm.

“River rises are expected,” the BOM website reads.

“Localised flooding is also expected in areas that receive heavy rainfall.”

Affected catchments could include the North Esk River, South Esk River, Meander River, Macquarie River, East Coastal Rivers north of Bicheno, Ringarooma River, North Coastal Rivers, Tamar near Launceston, Mersey River, Forth River, Northwest and Central Coastal Rivers and Arthur River.

Big swells to emerge in east after Ex-tropical cyclone

Surfers on Tasmania’s East Coast are set for a wild ride thanks to the effects of Ex-tropical Cyclone Seth.

Grey and gloomy days will be interspersed with a wet Thursday and Friday this week, as the effects of Seth are felt around the country.

Australia watched on Monday as large swells battered the Gold Coast and areas in Queensland and Bureau of Meteorology Tasmania duty forecaster Anna Forrest said unusual swells were similarly expected in parts of Tasmania later this week.

“There will be a decent north-easterly swell down the East Coast courtesy of the ex-tropical cyclone on Thursday and Friday,” Ms Forrest said.

Ms Forrest said the swells would reach around 2-3m; a figure not typically observed in the East.

“The unusual thing is the 2-3m is what you’d usually see on the West Coast and it’s going to swap around to be on the East Coast,” she said.

“West Coast is going to be under two metres by Thursday.”

Ms Forrest said the state would get a thorough rinse on Thursday and Friday, caused in part by the ex-tropical cyclone, but more largely prompted by a high pressure system south of Tasmania combining with a deep trough coming to the state from Victoria and inland NSW.

“We’re going to get an easterly onshore flow, it’s going to be very moist,” she said.

Rainfall was predicted to reach 60-120mm in the northeast and northwest, 30-60mm in the central north, and 20-50mm in other parts of Tasmania.

The East Coast could expect the state’s lowest temperatures, sitting around the high teens and low 20s.

“The place to be is probably going to be the West Coast because the winds are still going to be south-easterly right through until Friday evening when they finally go back around to the west and southwest,” Ms Forrest said.

Before the rainy change on Thursday, Hobart can expect grey and gloomy days with occasional showers.

Maximum temperatures of 19C have been forecast in Hobart for Tuesday and Wednesday, followed by highs of 20 and 24C on Thursday and Friday.

Saturday brings the chance of a thunderstorm in the morning over Hobart, with cloudy weather and possible showers forecast for both days on the weekend.
