A Flood Warning from the National Weather Service (NWS) Albuquerque continues for the San Juan River at Shiprock, New Mexico. Issued on October 24 at 4:11 PM MDT, the warning is expected to last until late Sunday night, October 26. Major flooding is occurring and is forecast, with the NWS anticipating catastrophic impacts at and near Shiprock. The river is likely near its crest, around or just above 22 feet, which is significantly higher than the bankfull stage of 13.5 feet. The last observed maximum river stage was 21.2 feet in the 24 hours ending Saturday at 4:00 AM MDT.

On Friday night, the San Juan River at Shiprock reached 17.3 feet, exceeding its 15.5-foot flood stage. Forecasters had predicted the river would peak at 20.7 feet late Saturday morning, just above the major flood stage of 20.5 feet. This event marks flooding not seen in generations, with water levels reaching historic highs. Upstream in Farmington, the river recorded 14.1 feet on Friday, surpassing a previous record of 12.3 feet set in 1909.

Widespread flooding has led to evacuations and numerous road closures across San Juan County. Approximately 600 homes in the Farmington and Shiprock areas were urged to evacuate. San Juan County Emergency Management has conducted 20 rescues in these areas. Police have warned families along the river from Farmington west through Upper Fruitland, Nenahnezad, San Juan Chapter, Hogback, and Shiprock to Montezuma Creek, Utah. San Juan County officials advise residents to heed emergency alerts and evacuate before rising floodwaters become life-threatening.

Navajo Nation President Buu Nygren and Shiprock Chapter Vice President Debra Yazzie have issued evacuation alerts for families living near the river. Shelters have been established in Shiprock at locations such as Power House Church and First Baptist. Navajo Police Deputy Chief Kee noted that emergency response resources are "stretched a little thin" due to the extensive flooding. Heavy rainfall, combined with snowmelt from the mountains, has been identified as a cause of the severe flooding. San Juan County Emergency Management has warned that while some floodwaters may recede, more rain is anticipated, and rivers are expected to rise again.
