The National Weather Service has issued warnings for extreme heat across 22 states, indicating that the heat index, or perceived temperature, may soar to 112°F in regions of the South and Gulf Coast. These advisories extend from Alaska to the Carolinas, encompassing the Plains, Midwest, Mountain West, and Southeast. Meteorologists are advising residents to remain indoors during the hottest parts of the day, maintain hydration, and check on elderly neighbors. Each year, heat poses the greatest weather-related risk in the United States, and officials warn that this week's heat dome may break daily temperature records in multiple states.
