The Bureau of Meteorology has issued a fire danger warning for the Ravensthorpe Shire Inland and Esperance Shire Inland regions.
The wild wind could also have a positive effect today, easing the smoke haze that has been hanging over Perth due to hazard reduction burns along the WA coast.
A cold front passing should bring some relief from the smoke in Perth tomorrow afternoon as winds shift northwesterly.
Meanwhile, a trough is bringing rain over south-western parts of the state with falls between five to 40 millimetres expected.
A weak trough is causing occasional showers in Tasmania with a high chance of rain in Hobart today.
