Here is what to expect:

• HEAT INDEX VALUES...Up to 116 due to temperatures in the upper 90s, and dew points around 70.
• TIMING...The highest heat index values will occur from the late morning into the early evening.
• IMPACTS...The heat and humidity may cause heat stress during outdoor exertion or extended exposure. The heat may be life-threatening to the elderly and those in poor health because of prolonged exposure without air conditioning, especially those in urban centers where low temperatures in the middle and upper 70s offer little relief. The heat and humidity may cause heat stress during outdoor exertion or extended exposure.
• PRECAUTIONARY/PREPAREDNESS ACTIONS...Take extra precautions: If you work or spend time outside, 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.

An excessive heat warning or heat advisory means that a prolonged period of dangerously hot temperatures will occur. The combination of hot temperatures and high humidity will combine to create a dangerous situation in which heat illnesses are likely, according to the National Weather Service.

Young children and pets should never be left unattended in vehicles under any circumstances. This is especially true during warm or hot weather when car interiors can reach lethal temperatures in a matter of minutes.

The added strain of dealing with days of heat and humidity can lead to higher energy costs and an increasingly greater threat of residents suffering heat-related illnesses, according to AccuWeather.
