Wind gusts of 90 to 100km/h are expected late this evening and Wednesday morning, the Bureau of Meteorology say. 

The state’s coast from Strahan, Smithon, Burnie, Devonport, Low Head and Bridport will be affected. 

Warnings are also in place for King Island and the Furneaux Islands. 

The upper East Coast and the lower East Coast will also be affected, including Swansea and Bicheno. 

The warnings are expected to remain in place until midnight on Wednesday, August 8. 

A small craft wind alert is in place for the Central Plateau Lakes.

The bureau has also issued a minor flood warning for the North Esk River.

Initial flood watch is also being carried out for the North West, North and Southern catchments. 

A strong north-westerly airstream developing ahead of a vigorous cold front, which is crossing early Wednesday morning, is to be blamed for the wild weather.

The bureau warns saturated soils in North and West Tasmania may make trees more susceptible to falling in strong winds.

In the South, tides are expected to be higher than normal all this week in preparation for a king tide on Friday. 

The higher tides are partly due to lower air pressure coinciding with the approaching king tide. 

The State Emergency Service advises people should: 

Supervise children closely.
