City officials urge residents to drink plenty of water before feeling thirsty, wear lightweight, light-colored clothing, and avoid strenuous outdoor tasks during peak heat. Vulnerable groups, including seniors and young children, should stay indoors and check in on neighbors. Utility providers in the region are preparing for increased electricity demand as air conditioners run overtime.
Thursday’s extreme heat mirrors similar advisories from recent summers, underscoring the need for ongoing caution. The Heat Advisory remains in effect until 8 p.m. Thursday, with additional alerts possible if conditions persist or intensify.
