At 1:48 p.m. Friday, the National Weather Service issued an update that keeps the heat advisory in effect for Comal County until 7 p.m. Sunday and lists heat-index values up to 109.
Comal County remains in the advisory area, where the weather service says heat and humidity may cause heat illnesses.
The revised ceiling is lower than the 112 listed in the earlier Comal.News report, but the warning and its weekend duration remain. Residents planning outdoor work, sports, travel or recreation still have three advisory details to track: the 109 ceiling, the Sunday evening deadline and any replacement alert.
The federal record identifies the notice as an update and classifies it as an actual event with expected urgency, moderate severity and likely certainty. Those labels describe the weather service’s current assessment rather than a guarantee that the alert will remain unchanged through Sunday.
