Heatwave Triggers Public Safety and Travel Alerts Across the U.S

Authorities across the United States have issued urgent safety and travel advisories as a severe heatwave continues to impact large portions of the country. The National Weather Service (NWS) has placed more than 90 million Americans under heat alerts, particularly in the Southwest, Southeast, and Midwest.

Temperatures in cities such as Phoenix, Las Vegas, and Dallas are expected to soar well above 105°F (40°C), with some areas facing record-breaking highs. Local health departments are warning of an increased risk of heat-related illnesses, especially for seniors, children, and those with chronic conditions.

Airlines have also issued statements, with several flights experiencing delays or cancellations due to extreme ground temperatures affecting equipment and scheduling.

In addition, highway departments are urging drivers to prepare for overheated engines, road closures, and increased risk of wildfires. Officials advise travelers to stay hydrated, avoid outdoor activity during peak sun hours, and monitor local alerts.

Emergency cooling centers have been opened in many cities, and residents are being urged to check on vulnerable neighbors.

This heatwave is being described as one of the most intense in recent years, prompting renewed discussions on infrastructure readiness and climate resilience.
