A critical flood watch has been issued for western El Paso, Texas, and southern New Mexico due to concerns over the structural integrity of the Cement Lake Dam, also known as the Portland Cement Reservoir. The National Weather Service (NWS) warns that a potential dam failure could lead to rapid and dangerous flooding in downstream areas, including Downtown El Paso, the Upper Valley, Sunland Park, Las Cruces, and southern Doña Ana County. The floodwaters are expected to carry hazardous debris, including razor wire, posing significant risks to residents. Residents are strongly advised to prepare for potential evacuation and monitor official alerts from local authorities and the NWS.
