Service Description: Accounting for the long-term influence of droughts and flooding within a region is difficult due to variations in the spatial extent and intensities over a period. Therefore, we created a cumulative drought severity index (CDSI) and cumulative moisture severity index (CMSI) for the United States using weighted monthly frequencies of Palmer Drought Severity Index values reported at climate divisions for the periods 1960 to 1989 and 1990 to 2019 (National Climate Data Center 2021). The occurrences of 'severe' conditions (index value of -3.0 to -3.9) receive a weight of 2 and 'extreme' (index value of a??? -4.0) receive a weight of 3 to reflect the increased magnitude of these events.
