The National Centers for Environmental Prediction's (NCEP)
Weather Prediction Center (WPC) is soliciting comments on the

The climatological significance is represented by Average
Recurrence Intervals (ARI) and Annual Exceedance Probabilities
of precipitation estimates from the NOAA Atlas-14, NOAA-40 and
Atlas-2. Full details are provided in the product description
document (Product Description).
Starting November 8, 2017, the experimental Extreme
