SOUTHWEST — Tuesday will bring a slightly higher risk of localized flooding across parts of Arizona, New Mexico, and Colorado, with Denver, Pueblo, Albuquerque, Flagstaff, and Santa Fe among the communities in the highlighted zone. Isolated to scattered monsoon thunderstorms are expected to develop during the afternoon as daytime heating combines with abundant moisture. Storms will persist into the evening, with some producing torrential downpours capable of triggering localized flash flooding.
Flooding Possible Across Broad Green-Shaded Zone
A wide area covering much of Colorado, eastern Utah, northern Arizona, and New Mexico falls within a zone where flooding is considered possible Tuesday, according to the latest monsoon outlook.
