The first fire ban of the season has been declared in north-western Victoria after firefighters were called to two blazes in the Mallee on Wednesday.
The weather bureau is warning the fire danger is severe for the Mallee and is predicting hot and dry north-westerly winds.
Temperatures hit 33 degrees Celsius in Mildura and Ouyen on Wednesday and are tipped to reach 37C at Kerang and Swan Hill.
Two fires broke out in the region yesterday, including one at a Beauchamp farm, south of Swan Hill.
The Country Fire Authority says it was started by farm machinery and burnt through 80 hectares.
There was another crop fire at Hattah, south of Mildura, which was also started by farm machinery.
From there it spread into a state forest.
Crews will be working to strengthen containment lines around that fire today.
