Short-term Drought Status Summary for April 2015

Note: The map to the left updates automatically on a weekly basis.

This summary below reflects changes from April 1 to April 28, 2015.

April was relatively dry statewide until the last week of the month. Temperatures around the state were warmer than normal in some locations and cooler than normal in others. Since April is normally a relatively dry month, short term drought conditions did not deteriorate. The rainfall at the end of the month was enough to continue the current drought levels for another couple of weeks, but not enough to improve the conditions. The rainfall will green up the grasses for a short period before the warm temperatures and winds dry them out again. This could lead to a busy wildfire season.

This report was produced by the Arizona Drought Monitoring Technical Committee, May 5, 2015.


Prepared by the Arizona Drought Monitoring Technical Committee, May 5, 2015

The next update in early May will reflect the conditions of April, May and June.


Arizona’s long-term drought status map is updated quarterly. The Monitoring Technical Committee determines the drought status for each watershed by comparing the precipitation and streamflow percentiles for the past 24-, 36- and 48 months to a 40-year historical record

Long-term Drought Status Update: January - March 2015

There is no change to the long-term drought conditions across the state. The only drought free area continues to be the in the Lower Gila and Lower Colorado River basins in the southwestern part of the state. Northern Arizona is abnormally dry as that is where the tail end of the few winter storms crossed into Arizona.

Unfortunately the majority of our winter storms were relatively dry or relatively warm, so snowpack was minimal this year across the higher elevations of northern Arizona and the Mogollon Rim. Roosevelt Reservoir is only slightly lower than this time last year due to water conservation efforts, but the Colorado River reservoirs are expected to drop much lower than this time last year due to dry conditions on the Upper Colorado watershed.
