) derived from a moisture balance model, using historical records of precipitation, temperature, and the local available water capacity of the soil. However, the Palmer hydrological drought index (PHDI) uses a modification of the PDSI to assess long-term moisture anomalies that affect streamflow, groundwater, and water storage. The primary difference between PDSI and PHDI is based on the ratio of moisture received to moisture required to definitely terminate a drought. The PDSI abruptly comes back to

being housed in the U.S. Drought Portal in a North American–specific site. These new tools would allow additional accuracy in the development of the NADM by allowing the overlay of information as well as increase the utility of the data by providing it in more accessible and useful formats. With minimal additional effort, a prototype Global Drought Monitor Portal (GDMP) could be developed as an outgrowth of the NIDIS portal modifications. The workshop recommended and the portal managers agreed to
