Extreme Heat Warning Today in the USA
As summer intensifies, much of the United States is currently under an extreme heat warning, with record-breaking temperatures sweeping across the country. The National Weather Service (NWS) has issued urgent alerts for millions of Americans, urging them to take precautions to avoid heat-related illnesses. With temperatures soaring well above 100°F (38°C) in several regions, understanding the risks and necessary safety measures is critical.
Rising Temperatures Across the Nation
The heatwave is affecting multiple states, particularly in the Southwest, South, and parts of the Midwest. Cities like Phoenix, Las Vegas, Dallas, and even portions of the East Coast are experiencing unusually high temperatures. Meteorologists attribute this surge to a persistent high-pressure system, also known as a "heat dome," which traps hot air and blocks cooler systems from moving in.
States Under Extreme Heat Warnings (June 13, 2025):
| State | Major Cities Affected | Forecast Highs (°F) |
|---|---|---|
| Arizona | Phoenix, Tucson | 110–115 |
| Texas | Dallas, Houston | 103–108 |
| Nevada | Las Vegas | 109–113 |
| California | Los Angeles, Palm Springs | 100–108 |
| Florida | Miami, Orlando | 95–100 (High Humidity) |
| Georgia | Atlanta | 95–99 |
| Illinois | Chicago | 93–97 |
The above cities are experiencing heat indices (how hot it feels with humidity) reaching up to 115°F in some cases, increasing the danger of heat exhaustion or heat stroke.
Health and Safety Risks of Extreme Heat
Extreme heat is one of the most dangerous weather events in terms of human health. According to the CDC, over 700 people die each year in the U.S. from heat-related causes, and thousands more suffer from heat-related illnesses.
Common Heat-Related Illnesses:
-
Heat Exhaustion – Symptoms include heavy sweating, dizziness, weakness, and nausea.
-
Heat Stroke – A medical emergency marked by high body temperature, confusion, and possible unconsciousness.
-
Dehydration – Excessive fluid loss can cause cramps, headaches, and fainting.
Those at greatest risk include the elderly, children, outdoor workers, and individuals with chronic illnesses.
How to Stay Safe During an Extreme Heat Event
It is essential to take precautions to avoid the harmful effects of the heat. The NWS and local health officials advise the following measures:
Top 10 Heat Safety Tips:

Climate Change and Increasing Heatwaves
Experts warn that extreme heat events are becoming more frequent and intense due to climate change. This week’s scorching temperatures align with global trends where summers are arriving earlier and lasting longer. Urban areas, in particular, experience what is known as the urban heat island effect, where buildings and concrete surfaces retain heat, pushing temperatures even higher.
Final Thoughts
Today’s extreme heat warning serves as a stark reminder of the growing threat posed by extreme weather. Whether you are in an affected state or preparing for upcoming heatwaves, staying informed and taking preventive measures can be life-saving. Authorities emphasize that heat-related illnesses are preventable — but only if the public takes the warnings seriously.
