Temperatures will soar past 40°C this week across southern Australia. South Australia, Victoria and New South Wales undergo the extreme heat. Saturday brings increased 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 heightens the risk of new fires starting. People should consume water often, avoid being outside during peak heat, and monitor fire warnings. Experts fear the mix of heat, dust and wind will test emergency teams.
