The Precipitation Processing System (PPS) is currently experiencing a hardware problem which is impacting PPS data production,  ftp archive access (arthurhou, trmmopen, etc.),  and PPS web sites (STORM, THOR, etc.) today - Tuesday May 10,2016.

Our system programmers are currently working on this problem and hope to restore services as soon as possible.  We will keep you informed as the situation changes.

We apologize for any inconvenience that this may have caused and appreciate your understanding and patience.
