Current ID/CPC Drought Criteria

Abnormal dryness

a.  Area has registered cumulative 4-week precipitation and soil moisture ranking less than the 30th percentile, with an SPI of 0.4 standard deviation below the mean.
b.  Area is expected to receive below-average precipitation (less than 80% of normal) during the outlook period.

Current ID/CPC Drought Criteria

Drought

a. Area must have previously been defined as “Abnormal Dryness”
b.  Area has continued to register seasonal precipitation and soil moisture deficits that have resulted in since the beginning of the rainfall season an eight-week cumulative precipitation, soil moisture, and runoff below the 20th percentile rank, and an SPI of 0.8 standard deviation below the mean
c.  Developing drought conditions must be supported by field observations, including impacts of moisture shortages on crops and water resources.

Current ID/CPC Drought Criteria

Severe Drought

a.  Area must have previously been defined as “Drought”
b.  Area has continued to register seasonal precipitation and soil moisture deficits that have resulted in since the beginning of the rainfall season a twelve-week cumulative precipitation, soil moisture, and runoff below the 10th percentile rank and an SPI of 1.2 standard deviation below the mean
c.  Severe drought conditions must be supported by field observations, including impacts of moisture shortages on crops and water resources.
