Drought Termination and Amelioration

Projected Palmer Hydrological Drought Index

The NOAA National Weather Service’s Climate Prediction Center produces official monthly and seasonal temperature and precipitation outlook products. This information was converted into projected monthly temperature and precipitation values for future months, then the projected values were used to compute projected future PHDI values.
