"Due to flooding that occurred at the Silver Spring data center on March 9, 2021, precipitation frequency estimates will not be available through the Precipitation Frequency Data Server (PFDS) until further notice. Teams are working to resolve the issues."
"Unfortunately the Precipitation Frequency Data Server (PFDS) is currently not available due to a significant facilities issue at a NWS data center on March 9. Teams are working to restore the capabilities but we do not have a time estimate for restoration of services.
In the meantime, if you let us know the location (latitude and longitude information in the decimal degrees) you need estimates for, we can provide the estimates to you in a tabular format. Best regards, HDSC"
