Around 134 million people in the United States have been placed under alerts as an "extremely dangerous and record-breaking" heat wave blankets a large portion of the country, warns the National Weather Service. Various regions, including the West Coast, southern Plains, lower Mississippi Valley, Ohio Valley, and parts of Florida, are anticipated to experience temperatures exceeding 90 degrees Fahrenheit (32 degrees Celsius). Moreover, triple-digit temperatures well above 37 degrees Celsius are expected in some areas.

Bob Oravec, a lead forecaster with the National Weather Service, highlighted that the Pacific Northwest will witness rising temperatures later in the weekend. Meanwhile, the state of Arizona continues to battle a wildfire near Phoenix, where firefighters work tirelessly amidst searing heat. Residents are also struggling with burns from scorching hot asphalt, concrete, and other surfaces.

The weekend heat wave is accompanied by increased humidity in certain regions, causing discomfort and health risks. Daniel Swain, a climate scientist with the University of California, Los Angeles, explained that when humidity combines with high temperatures, the body's natural cooling mechanism through sweat becomes less effective at maintaining a safe body temperature.

The timing of this dangerous weather pattern coincides with ongoing wildfires in northern California and a holiday weekend, raising concerns about potential risks. Meteorologist Chris Stachelski from the National Weather Service cautioned that during celebrations, individuals are more likely to become distracted and fail to stay properly hydrated. This can put them at greater risk of heat-related illnesses.

While it will require further research to establish a direct link between this particular heat wave and climate change, experts agree that human-caused climate change is contributing to longer and more intense heat waves. Although not surprised by the forecast for this weekend, Swain expressed concern about the escalating pace of heat and precipitation extremes resulting from climate change.

This heat wave stands out due to its expected duration, widespread impact, and high overnight temperatures, significantly increasing the health risks for individuals. Swain believes that this heat wave could be more consequential and dangerous than previous events that produced slightly higher temperatures.

As communities brace themselves for this scorching weather, authorities are urging residents to take precautions, such as staying hydrated, seeking shade, and avoiding prolonged exposure to the sun. It is essential to remain vigilant and prioritize personal wellbeing during this challenging period of sweltering heat.
