The combination of high heat and humidity poses risks of heat-related illnesses, particularly for vulnerable populations such as the elderly and those with pre-existing health conditions. The potential for heavy rain and localized flooding could impact low-lying and poor drainage areas, leading to hazardous travel conditions. Additionally, high ground-level ozone concentrations along the shoreline and southeastern Connecticut may exacerbate respiratory issues for sensitive groups, including children, the elderly, and individuals with asthma or other respiratory conditions.
