Rain! Rain!
It finally rained at our house this afternoon. Lord knows our plants and grass needed it. We get excited when it rains in the Valley of the Sun,since our average annual rainfall is only 4.5 inches
In Arizona, as in other regions of the world including India and Thailand, we experience a monsoon, a season of high temperatures, high winds, and high moisture, resulting in potentially deadly weather.
The term "monsoon" comes from the Arabic "mausim" meaning "season" or "wind shift."

Serious damage can occur from high winds, or from debris being tossed by those high winds. It is not unusual for trees to be downed, power lines to be damaged, and roof damage to occur.
When such high volume rain descends upon the Valley of the Sun, the ground and most especially the surface streets flood. Most roads in the area are not built to drain water quickly since such rain is too rare to justify the extra costs involved in constructing an elaborate drainage system. Quite often the rain pools on streets during and for a few hours after monsoon storms causing dangerous driving conditions.
