A heat alert is in effect across Missouri and Illinois, with dangerously high temperatures and a 105°F heat index expected to last through 9 p.m. Tuesday. This sweltering heat wave raises serious health concerns, especially for outdoor workers and vulnerable populations.
Heat Advisory Details
The National Weather Service in St. Louis has issued the Heat Advisory for more than 40 counties, stretching from Quincy, Illinois to Farmington, Missouri. The combination of triple-digit temperatures and high humidity will significantly increase the risk of heat-related illnesses, including heat exhaustion and heat stroke.
Affected Areas
The advisory covers major metro areas such as St. Louis, Columbia, Jefferson City, and Quincy, with St. Louis being one of the most affected cities. Residents across these areas are urged to take the following precautions to stay safe during the extreme heat:
- Limit outdoor activity, especially during the hottest part of the day (typically from 11 a.m. to 4 p.m.).
- Drink water frequently, even if you don’t feel thirsty.
- Check on vulnerable neighbors and family members, especially the elderly and those without air conditioning.
- Never leave children or pets in vehicles, even for a short time, as cars can heat up quickly.
Heat-Related Illnesses
Outdoor workers are particularly at risk, and OSHA recommends they take frequent breaks in shaded or air-conditioned areas. Heat exhaustion can occur quickly and is marked by symptoms like dizziness, heavy sweating, and nausea. Anyone experiencing these signs should immediately seek cooler surroundings and hydrate.
Outlook and Updates
The Heat Advisory remains in effect until 9 p.m. Tuesday, but additional alerts may be issued if the extreme heat persists. Stay informed through local weather alerts and be prepared for potential extensions of the advisory.
