The rainfall frequency atlases and technical papers published by the National Oceanic and Atmospheric Administration's (NOAA) National Weather Service (NWS) serve as national standards for rainfall intensity at specified frequencies and durations in the United States. The current standards were published between 1961 and 1973. The NWS is updating the standards for the semiarid southwest, the Ohio River basin and surrounding states, Hawaii, Puerto Rico, and the Virgin Islands. The results of the updates will be delivered in a variety of formats using a newly developed web portal. This paper describes the "Precipitation Frequency Data Server" and the variety of information and formats available.
