The heat wave poses significant risks to public health, particularly for vulnerable populations such as the elderly, children, and those with pre-existing health conditions. Heat indices in the Northeast could reach 100°F (37.8°C) to 105°F (40.6°C), increasing the risk of heat-related illnesses. In the West, extreme temperatures could lead to heat exhaustion or heat stroke, especially in areas like Southern California and Montana. Northern New England faces additional risks from severe storms on Tuesday, with potential for destructive winds exceeding 70 mph, large hail, and isolated tornadoes. Cities such as Burlington, Vermont, and Caribou, Maine, are under a level 3 of 5 severe weather risk.
