Northeastern US heat wave triggers record temperatures and event cancellations

A severe heat wave has swept the Northeastern United States, with Connecticut experiencing record highs of 100°F in Hartford and near‑record temperatures across the state. Air quality has deteriorated to unhealthy levels for sensitive groups, and isolated severe storms are expected later in the day. The extreme heat has already caused widespread power outages and a tree‑related injury in the state.

In neighboring New Jersey, temperatures are forecast to rise into the 90s with heat indexes reaching 100‑110°F, approaching the state's all‑time record. The National Weather Service has issued an extreme heat warning, prompting the cancellation or postponement of numerous Independence Day events, including parades, concerts, and park activities, though some fireworks displays will still proceed. Authorities advise residents to stay hydrated, limit outdoor exposure, and take precautions for vulnerable populations.
