Severe Heatwave Grips Eastern NSW, Raises Blackout Concerns

Temperatures in western Sydney soar to 40°C, prompting health warnings, power supply alerts, and preparations for volatile weather later in the week.

Eastern New South Wales is experiencing its most intense spring heatwave in four years, with temperatures reaching up to 12°C above average in some areas.
Western Sydney suburbs, including Penrith and Richmond, are forecast to hit 40°C, while Sydney's CBD is expected to peak at 33°C, with relief anticipated by Thursday or Friday.
The Australian Energy Market Operator has issued warnings about potential blackouts due to high electricity demand and outages at several coal-fired power plants, though risks have been partially downgraded.
NSW Health has issued heat safety guidelines, urging residents to stay hydrated, avoid outdoor activities during peak heat, and check on vulnerable individuals such as the elderly and pets.
A shift to stormy weather is expected later this week, with forecasts of heavy rainfall and potential flash flooding offering some respite from the heatwave.
