Introduction
An urgent heat advisory has been issued across several regions as temperatures soar to dangerous levels. With the summer heat reaching record highs, it’s essential to understand what a heat advisory means and how you can protect yourself and your loved ones. In this article, we’ll cover everything you need to know about heat advisories, including safety tips, health risks, and expert advice on staying cool.
What Is a Heat Advisory?
A heat advisory is a warning issued by the National Weather Service (NWS) when high temperatures and humidity levels are expected to pose a serious threat to human health. Typically, these advisories are issued when the heat index—a measure of how hot it feels—exceeds 100°F for a prolonged period.
Criteria for Issuing a Heat Advisory
- Heat index above 100°F for more than two hours
- High nighttime temperatures (above 75°F)
- Prolonged exposure to heat expected over consecutive days

Why Is a Heat Advisory Dangerous?
Extreme heat can lead to serious health problems, particularly for vulnerable populations like the elderly, children, and those with chronic illnesses. Here are the primary risks:
Common Heat-Related Illnesses
| Illness | Symptoms | Prevention |
| Heat Exhaustion | Heavy sweating, weakness, dizziness | Stay hydrated, avoid direct sun |
| Heat Stroke | High body temp, confusion, unconsciousness | Seek shade, emergency help |
| Dehydration | Dry mouth, dark urine, fatigue | Drink plenty of fluids |
Safety Tips During a Heat Advisory
1. Stay Hydrated
Drink water consistently throughout the day, even if you don’t feel thirsty. Avoid alcohol and caffeine as they can dehydrate you.
2. Avoid Outdoor Activities
Limit outdoor exercise and activities during peak heat hours (typically between 10 a.m. and 4 p.m.).
3. Use Air Conditioning
Stay indoors in air-conditioned spaces. If you don’t have AC, visit public places like libraries, malls, or cooling centers.
4. Dress Lightly
Wear lightweight, light-colored, and loose-fitting clothing to help your body stay cool.
5. Check on Vulnerable Individuals
Keep an eye on neighbors, friends, or family members who are elderly or have health conditions.
What to Do If You Experience Heat-Related Symptoms
If you or someone near you begins to show signs of heat exhaustion or heat stroke, take immediate action:
- Move to a cooler place
- Use cool cloths or take a cool bath
- Sip water
- Seek medical attention if symptoms worsen
How to Prepare for a Heat Advisory
Stock Up on Essentials

Run errands or do outdoor tasks early in the morning or late in the evening.
