The high heat and humidity levels pose risks of heat-related illnesses, especially for those spending extended periods outdoors. Heat index values exceeding 100°F (37.8°C) can lead to dehydration, heat exhaustion, or heat stroke if precautions are not taken. Vulnerable populations, such as the elderly, children, and outdoor workers, are particularly at risk. Additionally, the potential cold front later in the week could bring scattered thunderstorms, some of which may be strong, increasing the risk of localized disruptions.
