April 7-11 is Severe Weather Awareness Week. It’s a time where we help educate the public about severe weather preparedness, safety and the importance of weather awareness. Let’s take a closer look at extreme heat.
According to the National Oceanic and Atmospheric Administration, heat has caused more fatalities on average over the past decade than any other severe weather event. That’s why it’s crucial to understand what we can do to prevent heat-related illnesses.
Heat advisories and warnings
The National Weather Service issues advisories or warnings when the heat index is expected to pose a serious threat to public safety. The heat index is a measure of how hot it feels outside, taking into account both the air temperature and humidity.
Excessive heat outlooks are issued when there is a potential for an excessive heat event within the next 3 to 7 days. Excessive heat watches are issued when conditions are favorable for an excessive heat event within the next 24 to 72 hours.

Excessive heat warnings and advisories are issued when an excessive heat event is expected within the next 36 hours.
Heat-related illnesses
Everyone is at risk from extreme heat, but some people are more vulnerable than others.
Children, older adults, and individuals with chronic health conditions are especially susceptible to heat-related illnesses. That's why it's important to recognize the signs and symptoms of heat exhaustion and heat stroke, and know how to respond quickly.
Some helpful tips for avoiding heat-related illnesses are to:
Stay hydrated. Drink plenty of water throughout the day, even if you don’t feel thirsty.
Stay cool. Spend time in air-conditioned places, wear light clothing, and avoid strenuous activities during the hottest parts of the day.
Stay informed. Keep an eye on local weather alerts
We must also consider our pets during extreme heat. It’s important to leave animals at home during heat events, as the heat can be just as dangerous for them.
