US Heat Dome Peaks: 58 Million Under Alerts
13 Jul
Summary
- Record temperatures up to 110°F scorched western states.
- A heat dome trapped hot air, leading to widespread dangerous conditions.
- Extreme weather caused wildfires and historic flooding in multiple regions.
A potent heat dome reached its zenith on Sunday, impacting approximately 58 million individuals across the United States with severe weather alerts. Record-breaking temperatures, such as 110°F in Billings, Montana, were observed throughout the Great Basin, Rockies, and parts of the desert Southwest. This atmospheric phenomenon, which traps hot air, intensified heat across the West, with forecasts predicting a gradual eastward shift into the northern Plains early in the week.
Dangerous heat has also spread across the Dakotas, with Dickinson, North Dakota, exceeding its previous record high. Forecasters described the prolonged warmth as "exceptionally rare" for mid-July, warning of widespread highs between 105°F and 115°F, increasing wildfire risks and the likelihood of heat-related illnesses. Simultaneously, extreme weather events unfolded elsewhere; California experienced the Summit Fire near Los Angeles, while Colorado battled multiple wildfires, including one that destroyed over 850 structures. In contrast, parts of Louisiana and Missouri faced severe flooding, with New Orleans experiencing knee-high water and Missouri reporting historic flash floods that necessitated numerous rescues.
