NOAA Atlas 14

Does anybody know why the site is down and or another place I can get point precipitation frequency estimates?

RE: NOAA Atlas 14

The site is up today, but it's taking forever to load, so it's still not usable.

Looks down. Nothing but time outs.

RE: NOAA Atlas 14

"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."

From NOAA this morning:

"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"

That's a bit ironic. Hopefully they are updating the "Precipitation Frequency" database.

RE: NOAA Atlas 14

I was able to find some 100 year, 1 hour rainfall maps in Section 1106 of the International Plumbing Code.

RE: NOAA Atlas 14

May be old news...but site is back up!
