Extreme heat in the form of a widespread heat wave is reportedly affecting around 39 million people in the Western United States.
The excessive heat has placed many residents in California, Nevada, Montana, Oregon, and Washington under weather alerts during the Labor Day weekend.
While there were no immediate reports of casualties, the heat dome expansion has led to infrastructural disruption across the region, including blackouts and power outages in California and Nevada.
These latest developments were initially covered by Nature World News since the onset of September and serve as an update.
Excessive Heat in the West
AccuWeather Chief Meteorologist Jonathan Porter explained that all the risks associated with the extreme heat is more concerning than other heat waves.
This is because it will occur during the holiday weekend, where large number of people are spending time outdoors and could be less aware of the heat risks, Porter emphasized.
The meteorologist added that many tourists and vacationers are expected to visit heat-impacted areas this weekend; a time visitors could be less accustomed to extreme heat precautions, as cited by AccuWeather.
