Wednesday, July 19, 2017

The official start of the monsoon was June 15, but widespread activity started relatively late this year, especially in southern Arizona. There, numerous storms in mid-July brought widespread and frequent precipitation activity, boosting the percent normal monsoon precipitation in several locations. New Mexico had a comparatively earlier start to monsoon activity, which is expected given the typical spatiotemporal progression of the monsoon, and has seen more steady and widespread monsoon activity, as evidenced by the percent of days with rain.
