Marine Verification Stats on Demand

Upgrades Made to Marine Verification Stats on Demand


The Marine Verification Stats on Demand program has now been updated to include the ability to run reports by observation.  That means you can now look at verification of specific dates/times to help better identify performance in high impact events.  The program has also been modified to include performance statistics vs. model guidance.  

Website Offline

Website Will Unavailable from March 18 - 20, 2015


Due to major hardware upgrades taking place with our servers, we expect the Performance Management website will unavailable from March 18 - 20, 2015.  As a result of this outage, it is likely that it will take up to a full week for any of the daily product importers and verification matching routines to catch back up.  So we ask for your patience when the website becomes available again to allow for all the Stats on Demand interfaces to get caught back up with the latest data.  We apologize for any inconvenience this may cause and we appreciate your patience during this time.  If you have any questions, please email:

Storm Data Image

Images Now Allowed in Storm Data Again


We are very happy to announce that we have fixed the image caption bug that has plagued the StormDat program for many months now.  Unfortunately, this bug resulted in the Performance Branch having to turn off the capability to enter images associated with events all together.  

Now when you go into the StormDat program, you will once again be allowed to enter events.  Please feel free to go back and enter the image evidence for any event in which you had visual evidence, but were unable to upload it to the database because the feature was turned off.  If you encounter any issues or have questions, please contact: 

River Forecast Verification Report Image

River Forecast Verification is Back!


After a severe year hiatus, the Performance Branch has re-released the River Forecast Verification Stats on Demand program.  Now that it is back, the program is bigger and better, including the following enhancements:  reports with graphical output, CSV downloadable reports, daily running of verification data, and more ways to group data on the reports.
