ASHEVILLE, N.C. (828newsNOW) — Health officials are urging residents across Western North Carolina to prepare for several days of elevated heat this weekend and early next week, warning that prolonged exposure could pose health risks for vulnerable populations.

The North Carolina Department of Health and Human Services’ Climate and Health Program has issued heat-health alerts for multiple counties in Region 8, including Buncombe, Cherokee, Graham, Henderson, Macon, Madison and Mitchell.

According to the agency, heat index values are expected to reach between 85 and 87 degrees in affected areas from Saturday through Monday.

Graham County is forecast to experience the highest heat index values, reaching 87 degrees on Sunday and Monday. Buncombe, Cherokee, Henderson and Mitchell counties are expected to see heat index values of 85 degrees on Sunday, while Macon and Madison counties could reach 86 degrees on Sunday and Monday.

Health officials said temperatures of this magnitude can be dangerous, particularly for people who are more exposed to extreme heat or more sensitive to its effects.

Groups considered at higher risk include people without access to air conditioning, outdoor workers, older adults, pregnant women, people with disabilities, those with underlying health conditions and individuals who live alone.

To reduce the risk of heat-related illness, officials recommend drinking plenty of fluids, limiting outdoor activity during the hottest parts of the day and spending as much time as possible in air-conditioned spaces.

Residents are also encouraged to avoid caffeinated, sugary and alcoholic beverages, which can contribute to dehydration, and to watch for signs of heat exhaustion and heat stroke.

The state encourages residents to stay informed about local weather conditions and to check on family members, neighbors and others who may be vulnerable during periods of extreme heat.
