Temperatures will climb past 40°C this week across southern Australia. South Australia, Victoria and New South Wales face the most intense heat. Saturday brings extra dust from the Sahara. The dust will degrade air quality in several towns.
Northerly winds will accelerate bushfires more quickly in New South Wales and Victoria. This increases the risk of additional fires starting. People should stay hydrated with water often, avoid being outside during peak heat, and heed fire warnings. Experts fear the mix of heat, dust and wind will test rescue crews.
