Is Green Valley in a drought?
The simple answer to this question is Yes.  But, the complete answer may be more critical than a simples yes.  In the desert southwest, water sustainability is a major concern. According to a 2007 report by Pima County, 76,000 acre feet of water was pumped from the aquifer in the Upper Santa Cruz Valley in 2006, with 85 percent of that water being used for mining and agriculture. The remaining 15 percent was split between water used for golf courses and residential/commercial water use. The report explains that "The Green Valley area does not have a sustainable water supply given current groundwater pumping rates... the water table in Green Valley has been declining in past years, and is expected to decline even faster as water demands [continue to increase]...". The report concludes that "Water supplies will become critical within the next ten years." ^[1]

The Upper Santa Cruz Valley has several "major water users", all pumping water out of the same aquifer. None of these are owned by Pima County, the town of Sahuarita, nor Green Valley. The major water users are all private companies: ASARCO-Mission Mine, Phelps Dodge Sierrita Mine; Farmers Water Company; Sahuarita Water Company, Las Quintas Serenas Water Company, Quail Creek Water Company, Community Water Company of Green Valley, and the Green Valley Water District. The proliferation of water companies can be partially explained by the fact that the actual water in the aquifer is not owned by anyone, thus any amount of water can be pumped out, with costs limited only to drilling, pumping, distribution, etc. ^[2]

What's a dust devil?
A rotating updraft of air, originating from the ground, which is the result of warm air rising.  They are not associated with a thunderstorm and usually occur in hot open fields or desert terrains.  They are commonly seen in southern Arizona and care should be taken while driving in their immediate vicinity.

What's a gustnado?
This is a type of short-lived cyclonic circulation that can form with severe thunderstorms. While it derives its name from the tornado and is sometimes referred to as a weak, short-lived tornado, it has very little in common with tornadoes structurally.

What's a monsoon?
A monsoon is a thermally driven wind arising from differential heating between a land mass and the adjacent ocean that reverses its direction seasonally. You will often hear Arizonan's erroneously refer to the 'monsoons' as an individual or group of rainstorms. --> Read More at NOAA
