The National Weather Service in Dallas-Fort Worth has issued a heat advisory in effect from 1 p.m. Tuesday to 8 p.m. Wednesday.
Temperatures here are expected to be between 95 and 100 degrees both days, with heat index values of 105 to 110 degrees.
Heat exhaustion or stroke may set in if people and pets do not stay adequately cooled and hydrated, the National Weather Service warns.
"Be sure to check on persons with health problems and the elderly, as they are the most susceptible to heat exhaustion and heat stroke. Never leave young children or pets in an enclosed vehicle, even for a short time, as temperatures can quickly rise to life threatening levels," the advisory states.
"Take extra precautions if you work or spend time outside. 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. Heat stroke is an emergency — call 911."
