Monsoon 4
Monsoon 4 : What Happens During the Monsoon? Monsoon thunderstorms not only bring almost one-third of the annual rainfall in Maricopa County, they can also cause flash floods, lightning, strong winds, dust storms and hail. Monsoon thunderstorms have caused significant property damage and, unfortunately, several fatalities. Dust storms and flash floods contribute to numerous auto accidents. Every year, motorists ignore warning signs and barricades, and become trapped in low-lying flooded washes, forcing expensive and dangerous rescue operations by city and county emergency personnel. In addition, strong thunderstorm winds destroy fences and roofs, knocking down utility poles and creating power outages. Lighting kills two people every year in Arizona on average, with many more sustaining permanent injuries
