As Pittsburgh gears up to host the 2026 NFL Draft, the city is closely monitoring the potential for river flooding. The Allegheny River's water levels are rising due to recent heavy rainfall, prompting the National Weather Service to issue flood advisories for low-lying areas. Ongoing construction activities throughout the city may disrupt natural drainage patterns, exacerbating the risk of flooding. Construction sites can increase runoff into the river, further complicating the situation during periods of heavy rainfall.
