Department of Agriculture, National Drought Mitigation Center, National Oceanic and Atmospheric Administration <br /> <br />The drought status of most of the Intermountain West region remains esentially unchanged from last month, with the exception of <br />dryness persisting across southern Colorado, leading to an expansion of DO (abnormally dry conditions) into that area. In other areas <br />of the west, western Arizona moved into DO status and eastern Arizona moved into D2 (severe) drought status. Contrasting that are <br />portions of the Pacific North\:vest have moved out of drought. <br /> <br /> <br />'iill... .~;..- <br /> <br />,,0' <br /> <br />~ <br />I~~I <br />() <br /> <br /> <br />Drought Intensity <br />D DO Abnormally Dry <br />D D1 Drought - Moderate <br />.

The inset (lower left) shows the western United States from the previous month's map. <br />The U.S. Drought Monitor maps are based on expert assessment of variables including (but not limited to) the Palmer Drought <br />Severity Index, soil moisture, streamflow, precipitation, and measures of vegetation stress, as well as reports of drought impacts. It is <br />a joint effort of the several agencies; the author of this monitor is Rich Tinker NOAA Climate Prediction Center. <br /> <br />On the Web <br />For the most recent Drought Monitor, visit: http://www.drought.unl.edu/dm/monitor.html. <br />This site also includes archives of past drought monitors <br /> <br />RECENT CONDITIONS I 7 <br /> <br />
