The heat wave poses significant health risks, particularly for vulnerable populations such as the elderly, children, and those with pre-existing health conditions. Urban areas like Philadelphia and Trenton are expected to experience the worst conditions due to the heat island effect, which limits nighttime cooling. The combination of high temperatures and humidity increases the risk of heat-related illnesses, including heat exhaustion and heat stroke. Additionally, the heat wave may worsen drought conditions in the Mid-Atlantic and Southeast, as high temperatures accelerate evaporation and dry out soils. The abrupt transition from cooler spring weather to extreme heat may also make it harder for people to acclimate, increasing the potential for health impacts.
