Precipitation
frequency estimates

Hydrometeorological Design Studies Center is updating precipitation frequency (PF) estimates for various areas of the U.S. as Volumes of NOAA Atlas 14. Estimates in a variety of formats with supplementary information and documentation are available from the PF Data Server (PFDS). Publications for states not covered by Atlas 14 are also available.
Probable maximum
precipitation

National Weather Service (NWS) has provided probable maximum precipitation (PMP) guidance and studies since the late 1940s at the request of various federal agencies and with funding provided by those agencies. Probable maximum precipitation activities were discontinued in 1999 due to lack of funding, but copies of NWS PMP documents can be found on this site.

- NWS publications of interest for PF and PMP studies (NOAA Atlas 14, NOAA Atlas 2, Technical Reports, Technical Papers, Hydrometeorological Reports)
