'Silent killer': Sydney sizzles under severe heatwave as paramedics issue warning

Sydney is currently experiencing a heatwave, and experts are warning residents to be vigilant against the risks posed by what is being called a "silent killer." A total fire ban has been issued across the Greater Sydney region in response to the elevated fire risk brought on by the high temperatures.

Sydney experienced an unusually hot March morning, with temperatures already exceeding 28 degrees Celsius before sunrise. By midday, temperatures in parts of Western Sydney were approaching 36 degrees Celsius, while the city center reached around 34 degrees Celsius. The Bureau of Meteorology has issued a heatwave warning for the entire Greater Sydney region, with the heatwave extending as far as Broken Hill and Albury in New South Wales.

Steve Vaughan, Deputy Director of Emergency Management for NSW Ambulance, stated that a surge in emergency calls is expected due to the extreme heat. He mentioned that paramedics are prepared to respond to approximately 3,500 calls for assistance, emphasizing that emergency calls typically increase during hot weather. "It's March, and it's unseasonable to be seeing summer temperatures. It's a timely reminder that heatwave season is not over."

Vaughan described heatwaves as "silent killers" and advised people to pay attention to the elderly and children. He also warned against leaving children in cars. "Heatwaves are the biggest natural disaster killer, they take more lives than fire or floods. Never leave them in the car, the temperature inside can rise rapidly."

The hot weather is expected to last until midnight today, with cooler air arriving tomorrow. Meteorologist Magda Galos-Lorenz said, "Today is the hottest day, and then it's over - hopefully." NSW Ambulance has also warned Sydney residents to avoid going out during the hottest part of the day and advised them to "stay hydrated and avoid outdoor activity during the hottest part of the day."

With dry and hot gusty winds potentially exacerbating fires, the Rural Fire Service has advised residents in high-risk areas to activate their survival plans. A total fire ban has been declared for the Greater Sydney Region, Central Ranges, Southern Slopes and Southern Ranges areas.
