TUCSON, AZ (Tucson News Now) - Desert monsoon downpours can put a dent in drought. Back in 2006, the numbers added up to the sixth wettest monsoon on record. The U.S. Drought Monitor conditions at the start of that monsoon showed nearly 100 percent of the state experiencing drought conditions. The worst rating, Exceptional, covered parts of Southeast Arizona.
At the end of the monsoon, that Exceptional rating was erased, but drought still lingered over 75 percent of the state.
While our summer storms do help our drought, it is the winter rain and snow that really make a difference. That's because monsoon downpours come and go too quickly. Unlike the more gentle winter rain and snowfall, the water runs into washes before it has a chance to soak into the ground and destroy the drought.
