Residents across south-central Pennsylvania are being urged to take precautions as dangerously hot and humid weather continues, with the National Weather Service extending an Extreme Heat Warning through 8 p.m. Saturday.
Forecasters say the combination of high temperatures and oppressive humidity will create hazardous conditions that significantly increase the risk of heat-related illnesses, including heat exhaustion and heat stroke. The prolonged stretch of excessive heat is expected to persist through Saturday evening, offering little relief during the day.
The National Weather Service is advising residents to stay hydrated by drinking plenty of fluids, avoid prolonged exposure to the sun, and spend as much time as possible in air-conditioned buildings.
Those who must work or exercise outdoors are encouraged to take frequent breaks in shaded or air-conditioned locations. The Occupational Safety and Health Administration recommends scheduling regular rest periods to reduce the risk of heat-related illness during extended outdoor activity.
Young children, older adults and people with chronic medical conditions are especially vulnerable to extreme heat and should be monitored closely. Pet owners are also reminded to provide animals with plenty of fresh water and shelter from the sun and to avoid walking dogs on hot pavement, which can burn their paws.
Officials are encouraging everyone to become familiar with the warning signs of heat exhaustion and heat stroke. Symptoms of heat exhaustion may include heavy sweating, weakness, dizziness and nausea, while heat stroke is a medical emergency that can cause a high body temperature, confusion and loss of consciousness.
The extended period of high temperatures may also place additional strain on the electrical grid, increasing the possibility of localized power outages as demand for air conditioning rises. Residents are encouraged to prepare by keeping mobile devices charged and having flashlights and other emergency supplies readily available.
