An intense and prolonged heat wave is set to impact parts of the central and eastern United States in the days leading up to Independence Day.
Temperatures are expected to climb into the 90s and 100s (°F), with high humidity pushing heat index values to dangerous levels, ranging from 105°F to 110°F in some areas.

Impact & Risks

The heat wave poses significant health risks, particularly for vulnerable populations such as the elderly, children, and those with pre-existing health conditions. Prolonged exposure to such high temperatures can lead to heat-related illnesses, including heat exhaustion and heat stroke. Urban areas, where temperatures tend to be higher due to the heat island effect, are especially at risk. Residents in affected areas are advised to take precautions to avoid heat-related health issues.
