Safety Reminders

Given the active Heat Advisory and the high heat indices, it is critical to prioritize safety. Stay hydrated by drinking water frequently, even if you do not feel thirsty. Limit outdoor exertion, especially during the midday and afternoon hours when the sun is strongest.

If you must be outside, seek shade or air-conditioned spaces whenever possible. Check on elderly neighbors or those without reliable cooling to ensure they are safe. Wear lightweight, light-colored clothing and apply sunscreen if you are exposed to the sun for extended periods.
