Extreme Heat Watch issued ahead of weekend heatwave
An Extreme Heat Watch has been issued for all of Iowa, taking effect Saturday afternoon and continuing through Sunday evening. During this period, heat index values are expected to range from 105°F to 110°F, creating dangerously hot and humid conditions that could persist into early next week. This marks the beginning of a prolonged heat wave that starts Friday and may stretch across several days. The combination of high temperatures and oppressive humidity will make it feel significantly hotter than what the thermometer shows.
These extreme conditions dramatically increase the risk of heat-related illnesses, such as heat exhaustion and heat stroke—particularly for young children, the elderly, individuals with chronic medical conditions, and outdoor workers. The human body becomes less effective at cooling itself in such intense heat, especially when nighttime temperatures stay elevated, offering little relief.
Health officials are urging Iowans to take proactive precautions: stay well-hydrated, remain indoors in air-conditioned spaces whenever possible, avoid direct sunlight during peak hours, and check in on vulnerable family, friends, and neighbors. If you must be outside, wear light-colored clothing, take frequent breaks in the shade, and be alert to signs of overheating such as dizziness, nausea, or confusion.
This weekend’s heat is not just uncomfortable—it’s potentially dangerous. Stay tuned to Acute for real-time weather updates, safety tips, and alert notifications as this heat event unfolds.
