In an unprecedented event, approximately 130 million people across the United States are under heat warning or advisory as a record-breaking heatwave scorches the country from east coast to west. The sweltering temperatures have broken records in cities such as Ukiah, Livermore, Reno and Las Vegas among others. With dangerously high temperatures expected to continue into next week, forecasters predict that three-digit temperatures will be the norm in western US into the coming week.
The heatwave has been fueled by a ridge of high-pressure air that has parked over much of the West, preventing hot air near the surface from rising higher in the atmosphere. This phenomenon is causing cities such as Las Vegas, Phoenix and Portland to experience temperatures nearing or exceeding 100 degrees Fahrenheit.
The extreme heat poses a clear and present danger, particularly for children, elders, people with disabilities and those working outdoors. In response to the crisis, Governor Tina Kotek of Oregon has declared a statewide heat emergency. The prolonged duration of excessive temperatures is being attributed to climate change.
In addition to the record-breaking heatwave, wildfires have also been a concern in the west of the US. The Thompson Fire in Butte County, California has scorched almost 1554 hectares (3840 acres) since it started on Tuesday. Another fire, French Fire threatening Mariposa - a gateway to Yosemite National Park - has spread over 323 hectares (800 acres).
As the heatwave continues to impact millions of people across the country, experts are urging individuals to drink plenty of fluids, stay in an air-conditioned room or cool space, avoid direct sunlight and check up on relatives and neighbors. It is also important for young children and pets to never be left unattended in vehicles under any circumstances.
