Philly braces for triple-digit heat as city declares emergency

Philadelphia has declared a Heat Health Emergency and a Code Red as a multi-day heat wave drives temperatures into the 90s with heat indices around 100–110. The city is opening 50+ cooling centers, extending library hours, and conducting 24‑hour outreach for homeless residents; Code Red lasts from 11 a.m. Wednesday until further notice, and the Heat Health Emergency runs through 8 p.m. Saturday with possible extension. Air quality is Code Orange for ozone; SEPTA delays up to 20 minutes and Fourth of July events are shortened to reduce exposure. Residents should stay indoors with AC, stay hydrated, check on vulnerable neighbors, and use water refill points like Quench Buggies.
