The National Weather Service warned residents in the Brazos Valley area to take precautions while outside in hot temperatures Tuesday.
The weather service issued a heat advisory from 1 p.m. Tuesday to 7 p.m. Wednesday for southeast parts of north Texas, including Leon, Milam and Robertson counties. Weather service officials said dangerous heat-index values - how hot it feels - will reach between 105 to 110 degrees in the afternoon.
Actual afternoon temperatures will reach between 100 to 105 degrees on Tuesday and Wednesday, with overnight lows falling to between 75 and 80 degrees, according to the weather service.
The weather service also issued a hazardous weather outlook for portions of southeast Texas Tuesday, warning of high afternoon temperatures from 100 to 107 degrees in the area, which includes Madison, Grimes, Brazos, Burleson and Washington counties. Officials said temperatures are expected to continue to hit the same range through Friday.
Weather service officials warned against leaving young children or pets in enclosed vehicles - even for a short time - because temperatures can quickly rise to life-threatening levels.
People involved in vigorous outdoor activities should take frequent breaks, drink plenty of water and wear loose-fitting, light-colored clothing, according to the weather service. Weather service officials also suggested checking on people with health problems and the elderly, since they are the most susceptible to heat exhaustion and heat stroke.
