Heat Advisory Issued for Collin County as Highs Near 104, Anna Urges Precautions

The National Weather Service has issued a heat advisory for Collin County and surrounding North Texas counties, with actual temperatures expected to reach 99 to 104 degrees and heat index values climbing as high as 103 to 106 degrees. The advisory covers Dallas, Tarrant, Collin, Denton and neighboring counties, and forecasters say the hot, dry pattern is likely to continue with little relief until a weak front potentially moves through over the weekend. The City of Anna is using the advisory to renew its warnings to residents about the dangers of extreme heat. City officials say older adults, infants, young children and people with chronic medical conditions face the highest risk of heat-related illness during periods like this one. Air conditioning remains the most effective protection, according to the city, and residents without it at home are encouraged to spend time in air-conditioned public spaces such as shopping malls, libraries or designated heat-relief shelters. Officials also recommend drinking plenty of cool, non-alcoholic fluids regardless of activity level, and monitoring local news and weather updates for changes to the advisory. Residents in homes without air conditioning should keep blinds closed from morning through late afternoon to block direct sunlight and stay on the lowest level of the home when possible. The National Weather Service also urges limiting outdoor activity during peak afternoon heat hours and watching for early signs of heat exhaustion or heat stroke, including heavy sweating, dizziness, nausea and confusion. The advisory is the latest in a summer that has brought repeated stretches of triple-digit heat to North Texas, a pattern regional forecasters say is typical for the area's peak heat season in July and August.
