Wider weather episode

Abundant moisture and strong afternoon heating resulted in another round of numerous showers and thunderstorms with localized torrential rainfall. Atmospheric winds were favorable for back-building thunderstorms to produce repeated rounds of torrential rainfall around the high terrain. Several thunderstorms ended up producing rainfall rates over 2 inches per hour. The heaviest rainfall occurred within Guaje Canyon near Los Alamos, to the west of Sapello within the Sapello River basin, around Mexican Springs north of Gallup, and near Zuni Pueblo and Black Rock. The only flash flooding that was observed occurred near Black Rock where water was surging over highway 53 in several different locations.
