A dangerous heat dome is expanding across the central and southern United States, placing roughly 70 million people under heat advisories as temperatures soar well above 100°F (37.8°C) in many areas. The National Weather Service warns that the high-pressure system will remain nearly stationary through the week, trapping heat and humidity with little overnight relief, increasing the risk of heat-related illnesses.

The heat dome
This is the third major heat dome event in the past month, following a scorching early July that disrupted Independence Day celebrations and a mid-July wave that hit the Southwest and Great Plains.

Records may be broken around Denver, and western Nebraska is under an extreme heat warning with forecasts of 108°F (42°C). Source: AP News
Risks and recommendations
Children, older adults, and people with medical conditions are especially vulnerable. Authorities emphasize seeking air conditioning, staying hydrated, and limiting sun exposure.

Climate context
The frequency and severity of such heat events are linked to the human-caused climate crisis. According to Climate Central, "We are experiencing exactly what the climate models in the 1990s said we should experience now."
