Pasture, Rangeland, Forage (PRF)
Rainfall Index (RI) is based on weather data collected and maintained by the National Oceanic and Atmospheric Administration’s Climate Prediction Center. The index reflects how much precipitation is received relative to the long-term average for a specified area and timeframe. The program divides the country into six regions due to different weather patterns, with pilots available in select counties.
