The page will be updated as required. It was last changed on 715.11.2016.

• Latest change ((15.11.2016): The implementation date is confirmed as Tuesday 22 November 2016. The first operational run using the new cycle will be the 06 UTC analysis and forecast in the Boundary Conditions Optional Programme on 22 November followed by the 12 UTC main assimilation and forecast. The monthly forecast extension to the ensemble will be run with IFS Cycle 43r1 for the first time on Thursday 24 November 2016.
  

  In order to manage the transition, changes to dissemination requirements will be suspended from 09:00 UTC on 21 November 2016  to 09:00 UTC on 22 November 2016.
