Concise description:

Based on the original PDSI and modified to take into account longer-term dryness that will affect water storage, streamflow and groundwater. PHDI has the ability to calculate when a drought will end based on precipitation needed by using a ratio of moisture received to moisture required to end a drought. There are four drought categories: near normal, which occurs approximately 28%–50% percent of the time; mild to moderate, which occurs approximately 11%–27% percent of the time; severe, which occurs approximately 5%–10% percent of the time; and extreme, which will occur approximately 4% of the time.
