A heat advisory is in effect through Thursday evening, National Weather Service authorities said. 
The NWS issued a heat advisory at 2:40 a.m. Wednesday morning, effective from noon Wednesday until 7 p.m. Thursday. The advisory affects Lampasas, Coryell, Bell, Hamilton and surrounding counties. 
The advisory stated that temperatures are expected to be “between 96 and 101 degrees” during that time frame, with heat indices of “between 105 and 110 degrees,” NWS meteorologists said. 
A heat advisory means that afternoon heat index values are expected to meet or exceed 105 degrees for at least two consecutive days.
“Be sure to check on persons with health problems and the elderly, as they are the most susceptible to heat exhaustion and heat stroke,” authorities said. “Never leave young children or pets in an enclosed vehicle, even for a short time, as temperatures can quickly rise to life threatening levels.
“Take extra precautions if you work or spend time outside,” NWS officials continued. “When possible, reschedule strenuous activities to early morning or evening. Know the signs and symptoms of heat exhaustion and heat stroke. Wear light weight and loose-fitting clothing when possible and drink plenty of water.”

To reduce risk during outdoor work the occupational safety and health administration recommends scheduling frequent rest breaks in shaded or air-conditioned environments. Anyone overcome by heat should be moved to a cool and shaded location. 
Officials ask everyone to remember, “heat stroke is an emergency - call 911.”
