The flash flood threat in eastern Texas poses significant risks to low-lying areas and regions near rivers and streams. Severe thunderstorms in the eastern Great Lakes and Mid-Atlantic could lead to localized flooding, strong winds, and potential power outages. The northern Rockies may experience damaging winds and hail due to severe storms. Prolonged heat in the central and eastern states increases the risk of heat-related illnesses, particularly for vulnerable populations such as the elderly and those without access to air conditioning.
