NOAA’s Atlas 14 is a peer-reviewed publication that serves as the official government source of precipitation frequency values for the U.S. The new values are more accurate than estimates developed 40 to 50 years ago due to decades of additional rainfall data, an increase in the amount of available data, both in the number of stations and their record lengths, and improved methods used in the analysis.

Officials in locations that have seen significant increases are already assessing the potential impacts of adopting the new estimates based on NOAA’s preliminary data shared during the study’s peer-review process over the past year. “NOAA’s new rainfall frequency values for Texas will help state and local authorities better understand their flood risk and more accurately plan and design infrastructure to minimize the threat of flooding,” said Thomas Graziano, Ph.D., director, NOAA Office of Water Prediction.Ĭurrent standards used for infrastructure design and floodplain regulations will likely be revised based on the new values. They also help delineate flood risks, manage development in floodplains for FEMA’s National Flood Insurance Program and are used to monitor precipitation observations and forecasts that can indicate flooding threats by NOAA’s National Weather Service. ![]() DFW Weather Radar Doppler Severe Weather DFW Doppler Lightning Dallas Cam Counties: Warnings.
