More than two dozen North Texas counties — including Dallas and Tarrant counties — are under a heat advisory beginning at 1 p.m. Wednesday.
The National Weather Service said the heat advisory, which lasts until 8 p.m. Thursday, was issued because high temperatures will approach triple-digits, with heat index values exceeding 105 degrees across North Texas.
Weather experts warn that overexertion in these temperatures will lead to dehydration, which could then result in heat exhaustion or heat stroke.
Anyone who spends time outside should wear light-weight, loose-fitting clothing and drink plenty of water. If possible, reschedule strenuous activities to the early morning or late evening hours, the National Weather Service suggested.
They also advise checking on people with health problems and the elderly, as they are the most at risk of illness related to the heat, and never leaving children or pets in an enclosed vehicle, even for a short time.
