A Facebook post said dangerous heat will stick around in Mississippi through early next week, with heat indices reaching as high as 115°F in some areas. The post said the most dangerous conditions are expected from late morning through the afternoon each day.
The post advised that residents limit prolonged outdoor activity, especially during the hottest parts of the day, and drink plenty of water to stay hydrated. It said people should know the signs of heat illness and take action if they or someone else begins feeling sick.
The post warned never to leave children, older adults or pets in a vehicle and urged those who must be outside to take frequent breaks in a cool or shaded place. It also encouraged checking on family, friends and neighbors because heat can become dangerous quickly.
The heat index, which combines temperature and humidity, can make conditions feel much hotter and raise the risk of heat-related illness. This is a developing story and will be updated as more details emerge.
