The ongoing heat wave poses significant risks to vulnerable populations, including children, the elderly, and individuals with pre-existing health conditions. Prolonged exposure to high temperatures and poor air quality can lead to heat-related illnesses and respiratory distress. Nighttime temperatures will remain unusually high, barely dipping into the upper 70s°F (25°C), which may break record-warm nighttime lows. The lack of cooling relief overnight exacerbates heat stress, particularly for those without air conditioning.
