This publication contains hourly
precipitation amounts obtained from recording rain gages located at National Weather Service,
Federal Aviation Administration, and cooperative observer stations. Published data are displayed
in inches to tenths or inches to hundredths at local standard time. HPD includes maximum
precipitation for nine (9) time periods from 15 minutes to 24 hours, for selected stations.
Hourly Precipitation Data publication period of record begins October 1951. In some rare cases, there
are gaps in the archives available. Over the years that Hourly Precipitation Data
has been produced, there have been changes, improvements, and
additions to the monthly publications. Also, the climatic stations
available today have not always been available for publication.
This is an example of a
modern HPD Publication.
