Overview
- The National Weather Service has a heat advisory in effect Thursday from 11 a.m. to 8 p.m. for south-central and parts of eastern Pennsylvania and nearby New Jersey and Delaware counties.
- Forecasters expect heat index values around 100–102°F, which increase the chance of heat exhaustion and heat stroke for people exposed to high heat and humidity.
- The NWS advises drinking plenty of fluids, staying in air-conditioned spaces when possible, avoiding strenuous outdoor activity, and checking on children, older adults, pregnant people, and those with medical conditions.
- OSHA guidance for outdoor work during the advisory recommends frequent rest breaks in shaded or air-conditioned areas and limiting heavy tasks during the heat window.
- The advisory is a short-term public-health alert within a season of elevated temperatures, so local authorities and residents should watch updates and be ready to seek emergency care if signs of heat stroke appear.
