The heat poses significant health risks, particularly for individuals without access to cooling or hydration. Vulnerable groups such as the elderly, children, and those with pre-existing health conditions are at higher risk. The warm overnight temperatures exacerbate the situation by preventing the body from recovering. The heatwave coincides with major events like the Hardly Strictly Bluegrass festival and Fleet Week, which are expected to draw large crowds to outdoor venues, increasing the risk of heat-related illnesses.
