Heatwave Intensifies
A ‘potentially historic’ heatwave has settled over the West Coast, defying relief. The National Weather Service warns that this extreme heat will persist for several days.
Sweltering temperatures well into the 100s and 110s are scorching the region, with highs even reaching the 120s in the Desert Southwest.
Death Valley, California, could break daily records by topping 125 degrees, while Las Vegas, Nevada, faces the possibility of exceeding its all-time high of 117 degrees.
Health Risks and Precautions
Extreme heat is a significant threat, claiming lives every year. Residents are urged to stay indoors, keep hydrated, and take precautions against heat-related illnesses.
Cooling centers have been set up to provide relief, but the relentless heat poses a severe risk to vulnerable populations.

Wildfire Danger
The combination of extreme heat, gusty winds, and low humidity creates a tinderbox situation. Any wildfires that ignite will spread rapidly through already parched vegetation.
Red flag warnings are in effect across the West, signaling elevated wildfire risks.
The Thompson Fire in California’s Butte County has consumed over 3,700 acres, forcing evacuations and challenging firefighters under extreme conditions.
Eleven firefighters have been injured, eight due to heat-related illnesses. The fire remains 29% contained as of Thursday night.
State of Emergency
California is battling an active fire season, with 144,940 acres burned in 2024 compared to 7,812 acres at the same time last year.
Nearly two dozen wildfires are raging across the state, including the Thompson Fire.
The French Fire in Mariposa County triggered evacuation orders near Yosemite National Park.
California Governor Gavin Newsom declared a state of emergency for the Thompson Fire area, allowing for additional resources, including the potential mobilization of the California National Guard.

Data collected twice daily. Last updated July 5, 2024, at 4 a.m. ET. The maps show four risk categories: Minor affects very heat-sensitive people, especially if they’re outdoors without cooling or enough water; Moderate affects sensitive people and could impact some health systems and industries; Major affects anyone without cooling or enough water and is likely to impact health systems, industries, and infrastructure; and Extreme affects those without cooling or water during prolonged heat with no cool nights, and is likely to impact most health systems, industries, and infrastructure. Areas not shaded represent very low to no risk from heat.
