Subject:   Reminder: Removal of NCEP Model Analysis and

           Forecast Webpage: Effective August 30, 2011


On August 30, 2011, the National Centers for Environmental Prediction (NCEP) will remove the Model Analysis and Forecast (MAF) webpages, currently available at:



The NWS issued a Public Information Statement announcing NCEPs operational Model Analysis and Guidance (MAG) website:

The MAF and MAG websites showcase the NWS suite of graphical numerical model analyses and guidance and observational database. Based on the comments received from the PNS, NCEP declared the MAG operational on March 15, 2011, and will remove the older MAF website and all of its contents on August 30, 2011.

Some images available on the MAF site are now generated by the MAG. During periods when the numerical models are running and producing output, images on the MAF may lead (be available sooner than MAF indicates), lag (not be available as quickly), or not be available for a few minutes. 


A document is provided on the MAG website to guide users in transitioning to the new MAG-provided static image links. Users are strongly encouraged to transition to the new static image links when they become available.


For more information and updates, please refer to the MAGs Latest Information and News document at:
