The National Weather Service’s Saturday update keeps Comal County under a heat advisory through 7 p.m. Sunday, with heat-index values up to 111 expected.
Comal County is among the named advisory areas, where the weather service says hot temperatures and high humidity may cause heat illnesses. For residents, the advisory window covers the rest of Saturday and most of Sunday.
Issued at 4:48 a.m. CDT Saturday, the alert lists temperatures up to 105 and heat-index values up to 111. Its emergency-alert fields classify the message as an update with expected urgency, moderate severity and likely certainty.
The advisory area includes the I-35 corridor, the Coastal Plains and Burnet and Llano counties in the Hill Country. Comal appears in the alert’s named county list, along with neighboring Bexar, Guadalupe and Hays counties.
The National Weather Service attributes the risk to both hot temperatures and high humidity. That combination, the alert says, may cause heat illnesses while the advisory remains active.
This Saturday update follows Comal.News’ Friday advisory report. The next official change to watch is whether the weather service extends, replaces or allows the advisory to expire at 7 p.m. Sunday.
