Arizona Drought Monitoring Technical Committee
The Monitoring Technical Committee is responsible for gathering data about Arizona drought, climate, and weather; producing drought status reports; and disseminating that information to land managers, policy-makers, and the public.

Long-term Drought Status Update: October - December 2013
The late fall and early winter storms in November and December are responsible for most of the precipitation thus far in the water year (October 1 —September 30). That moisture led to some improvements to the long term drought conditions in January. However, the last three months have been extremely dry statewide, and that has resulted in downgrading the watersheds in northern, central and eastern Arizona.
The Lower Colorado, Lower Gila, San Simon, San Pedro, and Willcox Playa watershed in southern Arizona had no change, mostly due to the fact that they receive very little of their annual precipitation in the winter. The only area with no drought is Yuma and southern La Paz counties, and the lower Gila is borderline at abnormally dry.
The next update in July will reflect the spring conditions, and is not expected to show much improvement, as April through June are our driest months of the year.

The report for April - June 2014 will be posted in early August.
The Monitoring Technical Committee meets quarterly to discuss drought conditions throughout the state and produce the long-term drought status map. Long- term drought status for each watershed is determined by comparing the precipitation and streamflow percentiles for the past 24, 36 and 48 months to a 40-year historical record.
