Temperatures will reach past 40°C this week across southern Australia. South Australia, Victoria and New South Wales face the worst heat. Saturday brings extra dust from the Sahara. The dust will reduce air quality in several towns.
Northerly winds will drive bushfires at speed in New South Wales and Victoria. This increases the risk of new fires starting. People should stay hydrated with water often, avoid being outside at the hottest time, and heed fire warnings. Experts fear the mix of heat, dust and wind will test emergency teams.
