Flooding poses significant risks to affected areas, including impassable roads and potential property damage. The Santa Cruz River's elevated levels may impact downstream locations, while the Vamori Wash flooding has already rendered Highway 21 bridge approaches unusable. Residents in Marana, Santa Cruz, and Kupk are advised to remain vigilant as floodwaters continue to rise. Most flood-related fatalities occur in vehicles, emphasizing the importance of avoiding flooded roads.
