Around 70 million people across the central and southern United States are bracing for extreme temperatures this week as a third significant "heat dome" event develops.
This latest weather phenomenon, the third major heat dome to affect the country in the past month, is gathering strength, spanning a vast area from the Gulf of Mexico coast through the Great Plains and into the midwest.
Temperatures are expected to climb to between 35 and 40 degrees Celsius (95-105F), prompting widespread excessive heat advisories across the affected regions.
Millions Face Dangerous Temperatures
The persistent high-pressure system, known as a heat dome, traps hot air near the surface, leading to prolonged periods of intense heat and humidity. These conditions pose significant health risks, particularly for vulnerable populations, including the elderly, young children, and those with pre-existing medical conditions.
Around 70 million people across the central and southern United States are bracing for extreme temperatures this week.
Officials have issued warnings urging residents to take precautions, such as staying hydrated, seeking air-conditioned environments, and avoiding strenuous outdoor activities during the hottest parts of the day.
Growing Frequency of Extreme Heat Events
The recurrence of such severe heatwaves this summer aligns with broader climate trends indicating an increasing frequency and intensity of extreme weather events globally.
Scientists attribute the growing number of heat domes and record-breaking temperatures to climate change, emphasising the need for robust public health responses and long-term mitigation strategies.
Emergency services are preparing for a potential rise in heat-related illnesses as the scorching temperatures are expected to persist for several days.
