The combination of high temperatures and extreme humidity poses significant health risks, particularly for vulnerable populations such as the elderly, children, and those without access to air conditioning. The elevated dew points will make it harder for the body to cool itself, increasing the risk of heat-related illnesses. The National Weather Service warns that the Extreme Heat Warning conditions are hazardous for everyone, not just sensitive groups. Additionally, thunderstorms and heavy downpours may lead to localized flooding, and lightning poses a risk to outdoor activities. Coastal areas are under high surf and rip current advisories, with ocean water quality concerns due to recent rainfall.
