The flooding along the San Juan River is expected to cause severe impacts, including inundation of low-water crossings, making them impassable. Communities such as Mexican Hat, Bluff, Halchita, Montezuma Creek, and Aneth are at risk of significant damage. The river's rapid rise and high flow rates present dangers to residents and infrastructure. Emergency responders are urging residents to avoid crossing flooded areas and to remain vigilant as water levels continue to rise. This is a major flood event with potential for widespread disruption.
