Impact & Risks

The extreme heat poses significant health risks, particularly for vulnerable populations such as older adults, young children, and individuals with chronic health conditions. Prolonged exposure to high temperatures can lead to heat-related illnesses, including heat exhaustion and heat stroke. The lack of nighttime cooling exacerbates the risk, as heat stress accumulates over consecutive days. Additionally, the heat wave could disrupt infrastructure, including power grids and transportation systems, and increase the likelihood of water shortages. Residents in affected areas are urged to take precautions to avoid heat-related health issues.
