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: July - September 2014
Monsoon precipitation brought improvements to long-term drought, most notably in the Verde, Agua Fria, and Lower Colorado River watersheds. These three watersheds all improved by one category, and one watershed (Lower Colorado) has no drought.
The very wet monsoon likely caused some improvement on many other watersheds in central and southern Arizona (such as the San Pedro), but not enough to compensate for longer term drought conditions over the entire watershed.
The next update in early February will reflect the conditions of October, November and December.

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.
