Monthly Maps

Presented below are maps of Moisture Balance Drought Index (MBDI) values across the Colorado River Basin. The maps are updated monthly, and there is one map for each of the timeframes of 1, 3, 6, 12, 24, 36, and 48 months, which can be used to represent different forms of drought.

Represented on each map are classifications of drought or wetness that are stratified using the percentile values that represent the MBDI.
