The current atmosphere is notably muggy, with the air temperature at 82F but a feels-like temperature of 91F. Relative humidity sits at 84%, and the dew point is 77F, creating a sticky environment that feels heavier than the actual air temperature suggests.

Safety Reminders

With heat indices climbing into the mid-100s, the risk of heat-related illness increases significantly. It is crucial to stay hydrated by drinking water frequently, even if you do not feel thirsty. Limit outdoor exertion, especially during the midday hours when the sun is strongest.

Wear lightweight, light-colored clothing and seek air-conditioned environments whenever possible. Check on elderly neighbors or those without reliable cooling to ensure their safety during these oppressive conditions. There are no active weather alerts, but the heat itself poses a serious health risk that requires caution.
