The heat wave poses significant risks, particularly for those without access to air conditioning. Prolonged exposure to high temperatures and humidity can lead to heat-related illnesses, especially as nighttime temperatures remain elevated. Urban areas, where temperatures may not dip below 80 °F (27 °C), are at heightened risk. Vulnerable populations, including the elderly, children, and those with pre-existing health conditions, are especially susceptible. The heat index, which accounts for humidity, will make outdoor activities and strenuous work dangerous during peak hours.
