The heat wave poses significant risks to public health, particularly for those without access to cooling or hydration. Heat index values in some areas are reaching triple digits, increasing the likelihood of heat-related illnesses. Major cities from Richmond, VA, to Boston, MA, are expected to experience the brunt of the heat. In southwest Texas, saturated soils from heavy rainfall could lead to dangerous flash flooding, with storm-total rainfall expected to reach 6-8 inches in many areas and over 10 inches in isolated spots. Vulnerable populations, including children, the elderly, and outdoor workers, are at heightened risk.
