ALT The National Weather Service (NWS) Heat Index Chart. A large grid crosses air temperature (80°F to 110°F on the top horizontal axis) with relative humidity (40% to 100% on the left vertical axis) to calculate the "apparent temperature" or how hot it feels. The background is a color gradient that shifts from yellow on the top-left to deep red on the bottom-right as heat and humidity rise. For example, at 90°F and 70% humidity, the heat index is 106°F. Text on the right reads: "The Heat Index measures how hot it actually feels outside. The Heat Index level that is considered dangerous can vary by person and region." Fine print at the bottom states: "The Heat Index is a product of NOAA’s National Weather Service (NWS)."

ALT A graphic showing ways to recognize and treat heat exhaustion and heat stroke. Symptoms of heat exhaustion include dizziness, thirst, heavy sweating, nausea, and weakness. If someone is experiencing heat exhaustion, move them to a cooler area, loosen clothing, sip cool water, and seek medical help if symptoms don't improve. Heat exhaustion can lead to heat stroke. Symptoms of heat stroke include confusion, dizziness, and becoming unconscious. If someone is experiencing heat stroke, call 911, move them to a cooler area, loosen their clothing and remove extra layers, and cool them with water or ice. Heat stroke can cause death or permanent disability if emergency treatment is not given. Stay cool, stay hydrated, and stay informed!"
