NOAA Atlas 14 Volume 11 precipitation frequency estimates, Kerrville

Summary. NOAA Hydrometeorological Design Studies Center point precipitation-frequency estimates (Atlas 14 Vol. 11, Texas) for the Kerrville gauge location: depths for 5 min to 60 day durations and 1 to 1000 year return periods with 90 % confidence bounds.

Scenarify role. Design storms for Rain scenarios. Scenarify's KOSTRA generator is Germany-only, so Atlas 14 depths are entered as uniform block rain or converted to a hyetograph CSV (Time<datetime>;Precipitation Depths<double>[mm]).

Access. PFDS CSV API, no auth: https://hdsc.nws.noaa.gov/cgi-bin/hdsc/new/cgi_readH5.py?lat=<lat>&lon=<lon>&type=pf&data=depth&units=english&series=pds. Change units=metric for mm.

Format and CRS. CSV text; point query by WGS84 lat/lon.

Coverage. Point estimate at 30.0533 N, 99.1634 W (USGS 08166200); re-query for sub-basin centroids.

Provenance and caveats. Atlas 14 Vol. 11 (2018) is based on records through ~2017; the July 2025 event exceeded the 1000 year 6 h estimate locally, so consider the upper confidence bound for stress tests.
