Torrential rains have washed away a Central Highlands road as a flood watch remains current for northwest and central coast river basins.
Lake Augusta Road at Liaweenee has been deemed four-wheel drive only after more than 60 millimetres fell overnight Monday.
Weather Bureau Meteorologist Deb Tabor says inclement weather will hit the north and northeast later in the week, with locally heavy falls forecast north of Swansea.
"The Central North and North East will really cop a hammering in terms of low-level, very strong southeasterly winds. For the rest of Wednesday once it increases late in the morning it'll keep going into the afternoon, evening and all through Thursday," she said.
A severe thunderstorm warning was issued for the West and North West late on Monday afternoon, giving a few hours notice to prepare for heavy rain and damaging winds.
By early on Tuesday morning, Strahan had received an inch while more than 40 millimetres had fallen at Low Rocky Point.
"[We had] High falls around the Western Tiers and parts of the West - just northeast of Strahan - around 60-65 millimetres for some places through there. Liaweenee around 65, same with Lake Augusta, Waratah had 47 and Luncheon Hill around 45," Ms Tabor said.
A number of rivers are on flood watch: the North Esk, Meander, Macquarie, Ringarooma, Mersey, and Forth.
UPDATE 12pm Tuesday:
A severe weather warning for damaging winds has been issued for the North and North East of the state, including Launceston, St Helens, the Furneaux Islands and Bicheno.
The Bureau of Meteorology says the Central Highlands is also likely to be affected.
Damaging southeasterly gusts averaging 60 to 70 km/h are expected, while some high altitude areas could get speeds up to 110km/h.
The winds are due to ease on Thursday.
