At 1:30 a.m. Thursday, the National Weather Service issued an update continuing Comal County’s heat advisory until 7 p.m., with temperatures up to 104 and heat-index values up to 110 expected.
People working, traveling or spending time outdoors in Comal County face an elevated risk of heat illness through Thursday evening. The weather service says hot temperatures and high humidity may cause heat illnesses, making the alert’s remaining hours especially consequential for anyone whose Thursday plans keep them outside.
By 1:30 a.m. Thursday, an active, actual alert covered Comal and seven neighboring counties. The federal alert record classifies the event as moderate in severity, expected in urgency and likely in certainty. Those labels describe the agency’s current alert assessment; they do not change its listed end time.
The advisory area includes Comal, Hays, Bexar, Guadalupe, Atascosa, Wilson, Karnes and DeWitt counties. The alert provides expected maximums for that eight-county area rather than a reported observation from one Comal County weather station, so conditions at a particular location may differ during the day.
