The flood watch primarily affects areas west of the Continental Divide, including Gallup, Farmington, Shiprock, the Four Corners, and the western mountains. The main concern is 'training,' where multiple storms follow the same path, leading to rapid rainfall accumulation and potential flooding. Low-lying areas, valleys, and regions with poor drainage are particularly vulnerable. Strong thunderstorms may also bring gusty winds and lightning, posing additional risks to residents and infrastructure.
