The potential for severe weather could significantly impact the thousands of people expected to attend the weekend's events in Pittsburgh. Outdoor activities, including the Arts Festival and Pride celebrations, may face disruptions due to rain, wind, or other adverse conditions. Concertgoers at the Morgan Wallen performances should also be prepared for possible delays or cancellations. The risks include reduced visibility, slippery surfaces, and potential hazards from strong winds or lightning, which could pose safety concerns for large gatherings.
