The Probabilistic drought forecast is based on the North American Multi-Model Ensemble (NMME), which is an experimental multi-model seasonal forecasting system consisting of coupled models from US modeling centers including NOAA/NCEP, NOAA/GFDL, IRI, NCAR, NASA, and Canada's CMC. The hindcast and real-time prediction NMME data is readily available and in graphical format from CPC . The NMME forecast are currently being used as guidance for operational forecasters. The probabilistic SPIx forecasts is performed in real time operationally and results presented at the drought briefing.
