Heavy Rain and Flash Flood Watch for New Mexico
A significant monsoon surge is expected to bring widespread heavy rain and thunderstorms to New Mexico starting Tuesday, September 22, 2026. A gusty cold front will move west through the central mountains Monday night, increasing moisture levels across the state. By Tuesday evening, atmospheric moisture could approach record levels for late September, leading to widespread showers and thunderstorms. Areas such as Albuquerque, Santa Fe, Roswell, and Ruidoso are expected to experience heavy rainfall, strong wind gusts, hail, frequent lightning, and flash flooding. A flash flood watch is already in effect for parts of the region through 6 p.m. Wednesday, with the possibility of extension. Tuesday night will see steadier rain with embedded thunder, continuing into Wednesday, which is forecasted to be the wettest day of this weather pattern.
