Impact & Risks

The extreme heat poses significant risks to vulnerable populations, including children, the elderly, and outdoor workers. Prolonged exposure can lead to heat exhaustion or heatstroke, which is life-threatening when core body temperatures reach 104°F (40°C) or higher. Pets are also at risk if left outside or in vehicles. Additionally, the dry conditions may elevate the likelihood of grass fires, further endangering the region. Residents are urged to take precautions to avoid heat-related illnesses and to monitor local fire conditions.
