Wider weather episode

The upper-level high pressure system was located over the Great Basin area on August 16, 2022, while a backdoor front moved into eastern New Mexico before stalling along the east slopes of the central mountain chain. Increased moisture and favorable upslope flow supported increasing thunderstorm coverage across much of northeast New Mexico. With already saturated soils from an active monsoon season, the stage was already set across this area for flash flooding. New Mexico's largest burn scar was hit once again with strong thunderstorms producing heavy rainfall, flooding areas that have been repeatedly hit this summer. Meanwhile, heavy rain also impacts northwest New Mexico near the Arizona border, causing devastating flash flooding around Sheep Springs.
