Due to dangerously high temperatures expected over the next 24-plus hours, the National Weather Service in Huntsville has issued an Excessive Heat Warning for north Alabama, which is in effect from Monday, 7 p.m., to Tuesday, 6 p.m.
The heat index is being valued as high as 114 degrees due to temperatures in the upper-90s and dew points in the mid-70s.
The National Weather Service stated the heat advisory would expire at 7 p.m. Monday and be replaced with an excessive heat warning starting at that time. It is expected to last through 6 p.m. Tuesday.
Areas include Madison, Marshall, Cullman, Morgan, Limestone, Lawrence, Franklin, Colbert and Lauderdale counties, according to the National Weather Service in Huntsville.
An Excessive Heat Warning 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.
Dangerously high temperatures and humidity could quickly cause heat stress or heat stroke if precautions are not taken, according to the National Weather Service. Take extra precautions if working or spending time outside. When possible, reschedule strenuous activities to the early morning or evening hours. 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.
Know the signs and symptoms of heat exhaustion and heat stroke. If you believe someone is having a heat stroke, call 9-1-1 immediately.
