Storms
Tropical storms are one of Arizona's main sources of rainfall, as they infuse the monsoon over the southwestern United States with moisture, producing large-scale floods in occasions. However, all of the storms that have impacted Arizona have formed in the latter parts of the Pacific hurricane season, and only storm remnants have affected the state before August.

Famous quotes containing the word storms:
“You don’t need to pray to God any more when there are storms in the sky, but you do have to be insured.”
—Bertolt Brecht (1898–1956)
“In the midst of this chopping sea of civilized life, such are the clouds and storms and quicksands and thousand-and-one items to be allowed for, that a man has to live, if he would not founder and go to the bottom and not make his port at all, by dead reckoning, and he must be a great calculator indeed who succeeds.”
—Henry David Thoreau (1817–1862)
“Mozart has the classic purity of light and the blue ocean; Beethoven the romantic grandeur which belongs to the storms of air and sea, and while the soul of Mozart seems to dwell on the ethereal peaks of Olympus, that of Beethoven climbs shuddering the storm-beaten sides of a Sinai. Blessed be they both! Each represents a moment of the ideal life, each does us good. Our love is due to both.”
—Henri-Frédéric Amiel (1821–1881)
