Heat Advisory Issued for Summit Through Wednesday as Temperatures Soar

Maria Torres · Union County Life

The National Weather Service issued a heat advisory for Summit and surrounding Union County municipalities through Wednesday evening, as combination high temperatures and humidity levels push heat index values toward triple digits. City officials and emergency responders advise residents to take precautions to prevent heat-related illnesses during the period of extreme weather.

City emergency management personnel urge residents to stay indoors in air-conditioned spaces during peak heat hours, drink plenty of water, and avoid strenuous outdoor activities between mid-morning and early evening. Union County Life confirmed that public cooling locations, including the Summit Free Public Library and municipal community spaces, are available to offer relief for residents needing air-conditioned shelter.

First responders emphasize checking on elderly neighbors, young children, and pets during severe heat events. Health officials warn that high heat index values increase the risk of heat exhaustion and heat stroke, advising residents to recognize symptoms such as dizziness, heavy sweating, nausea, and rapid pulse.

Pet owners are reminded never to leave animals inside parked vehicles and to restrict dog walks to grassy areas during early morning or late evening hours to protect paws from scalding pavement.

Summit residents seeking information on municipal cooling centers, emergency shelter services, or weather advisories can contact the Summit Fire Department or Police Department non-emergency lines at nine zero eight two seven three zero six zero zero or visit cityofsummit.org.
