Understanding Excessive Heat Warnings: What You Need to Know

An excessive heat warning is a serious alert issued by the National Weather Service (NWS) when extremely dangerous heat conditions are expected. But what does it mean, and how can you stay safe?

What Triggers an Excessive Heat Warning?

The NWS issues an Excessive Heat Warning when the maximum heat index temperature is expected to be 105° or higher for at least 2 days, and nighttime air temperatures will not drop below 75°. However, these criteria vary across the country.

Heat Index: What's the Difference?

The heat index measures how hot it feels outside, taking into account both temperature and humidity. It's essential to understand the heat index, as it can make a significant difference in how hot it actually feels.

Extreme Heat Warnings: Not to Be Ignored

Excessive heat warnings are not just a mere inconvenience – they can be deadly. According to the NWS, extreme heat is the leading weather-related killer in the U.S. It's crucial to take necessary precautions to stay safe during extreme heat events.

Stay Safe During an Excessive Heat Warning

During an excessive heat warning, it's essential to stay hydrated, stay indoors, and avoid strenuous activities. Monitor those who are at high risk, such as the elderly and young children, and be aware of the warning signs of heat-related illnesses.

Remember, an excessive heat warning is not just a warning – it's a call to action. Take necessary precautions to stay safe and healthy during extreme heat events.
