Surviving the Unprecedented Heat Wave Sweeping Across 15 States

The summer heat is upon us, and it's hotter than ever! An unprecedented heat wave has swept across 15 states, affecting more than 112 million people.

The National Weather Service has issued heat alerts for these states, warning people to take precautions against the extreme heat.

This heat wave is expected to break longstanding records, especially in the Southwest, and the duration of the event that's set to continue well into next week increases public health dangers.

Extreme heat is the top weather-related killer during an average year in the U.S., according to the NWS.

Heat waves can be extremely deadly, particularly when high temperatures are persistent and there is a lack of significant cooling at night.

To stay safe during heat waves, it's essential to stay hydrated, avoid prolonged exposure to the sun, and remain indoors in air-conditioned spaces as much as possible.

Cities in the Southwest that are synonymous with heat are poised to break daily, monthly, and potentially all-time high-temperature records during this event.

For example, Phoenix is on track to either tie or break its record of 18-straight days with highs of 110°F or above.

Las Vegas may see its hottest temperature on record of 117°F tied or exceeded during this heat wave.

Many studies show that heat waves are more likely, longer-lasting, and more intense as global average surface temperatures increase.

New analysis from Climate Central shows that climate change is likely boosting the odds for the upcoming extreme heat in Arizona by at least a factor of four.

By taking simple precautions and staying informed, you can stay safe and healthy during heat waves and other extreme weather events.
