When temperatures spike, your local weather service might issue a "Heat Advisory" or a "Heat Warning," and knowing the difference can literally keep you safe. You might think they're interchangeable, but these terms signal distinct levels of danger and require different actions to protect yourself.
Heat advisories are trending because extreme heat is becoming more common and dangerous, leading to increased public health concerns.
Globally, 2023 was the hottest year on record, and 2024 is projected to continue this trend.
