Allegheny County and Pittsburgh sit at the confluence of the Allegheny, Monongahela, and Ohio Rivers — a geography that creates serious and recurring flooding risk. June 2022 flooding caused catastrophic damage across the county including destroying the Forbes Avenue bridge. Pittsburgh has flooded repeatedly throughout its history. The city's steep hillsides add landslide risk during heavy rainfall.

  • Store at least 72 hours of food and water.
