Safety and Alerts

There are no active National Weather Service or NOAA weather alerts in effect for Denison at this time. However, the combination of high temperatures and elevated humidity requires caution. The heat index values approaching 102F mean that it will feel significantly hotter than the actual air temperature.

Residents should stay hydrated and limit prolonged outdoor exertion during the peak heat hours. Check on neighbors, especially the elderly or those without air conditioning, to ensure they are safe in the rising temperatures. Layering up is not necessary, but protecting against the sun and heat is essential for the coming days.
