Crop Moisture Index


        About this map:
The Crop Moisture Index map more rapidly depicts changes in drought and rainfall conditions than the Palmer Index map and thus can change considerably from week to week. It is also more effective in calculating abnormal dryness or wetness affecting agriculture as was designed to indicate normal conditions at the beginning and ending of the growing season. 
The CMI map 
uses the same scale as the Palmer Index map.



 
 
 
  Drought Index
 
 
        About this map:
The Palmer Index map depicts long-term (several months) more than short-term (several weeks)
drought. Negative values 
indicate areas of drought--lower numbers being areas of more severe 
drought. The Palmer Index is standardized to local climate,
so it can be applied to any part of the
country to demonstrate relative drought or rainfall conditions. However, it is not 
particularly useful in calculating supplies of water locked up in snow, and thus works best east of the Continental Divide.
