Alerts and safety reminder

There are no active NWS/NOAA weather alerts for Denison at this time.

With humidity and heat both elevated, it is a good idea to take the weather seriously even without an alert in place. Drink water, take breaks when working or exercising outdoors, and try to limit the hardest activity during the hottest conditions. Check on people who may be more sensitive to heat, including older adults, young children and anyone without reliable cooling.
