• Description:
  The report and included maps represent an update of the information contained in the precipitation-frequency atlas, published by the National Weather Service in 1973 (NOAA Atlas 2). Data collection for the National Weather Service (NWS) study ended in 1966. The new study includes the 40-years of precipitation record collected since 1966 as well as additional data from sources not available in 1966. These additional data provide a precipitation database with more than double the record that was available in the original NWS study.
  
  In addition to the much expanded dataset, there have been major advances in the methods for statistical analysis of precipitation annual maxima, and for spatial mapping of precipitation in complex terrain. L-Moment statistical analysis techniques, conducted within a regional framework, have greatly improved the reliability of precipitation magnitude-frequency estimates.
