Why it matters
The Grand Canyon is a major tourist destination, and severe weather events pose a significant risk to its operations and the safety of millions of visitors. Disruptions caused by flash flooding or heavy rain can lead to substantial economic losses for the park and surrounding communities, impacting tourism revenue and infrastructure maintenance.
Arizona is known to be susceptible to extreme weather patterns influenced by climate phenomena like El Niño. This event compounds the long-term risks associated with changing climate, meaning that the frequency and intensity of rainfall events that threaten the Grand Canyon may increase over time.
