Millions of residents across the US Midwest, Northeast, and parts of Canada are under heat advisories. The extreme temperatures pose significant health risks, particularly for vulnerable populations such as the elderly, children, and those with pre-existing health conditions. Poor air quality further exacerbates these risks, especially for individuals with respiratory issues. The heatwave has already contributed to 44 deaths earlier this month, underscoring the severity of such events. Additionally, the incoming cold front may lead to severe thunderstorms, increasing the risk of localized flooding and wind damage in affected areas.
