The storm system poses risks of flash flooding, especially in low-lying and flood-prone areas. Rivers and streams, including the San Juan and Animas Rivers, are rising, increasing the potential for river flooding. In Pagosa Springs, mandatory evacuations highlight the severity of the situation. Severe thunderstorms in New Mexico could bring large hail, damaging winds, and isolated tornadoes, particularly in areas like Socorro. The risk of flash flooding will extend into central and eastern New Mexico over the weekend.
