A meteorological event occurs during July and August as Arizona’s landscape heats up and the wind changes direction bringing monsoon thunderstorms over Grand Canyon.
In fact, the name “monsoon” is derived from the Arabic world “mausin” meaning season or wind-shift.
During the winter, winds blow primarily from the west or northwest then summer winds shift from the south or southeast.
This brings moisture northward from the Pacific Ocean and the Gulf of Mexico.
Three stages of thunderstorm develop: the updraft cumulus, mature stage and dissipation.
Storm cells in Arizona are generally short-lived and average about 30-40 minutes. Of course the cycle can repeat itself so always be prepared for monsoon thunderstorms over Grand Canyon.
