They will be processed after the outage is completed.

Latest day ahead and within day national demand and wind generation forecasts and daily actual temperature reports will also be affected. The latest updates to these will be published on BMRS after the outage is completed. 

Do I need to take any further action?

You do not need to take any specific action but just note the impact of the outage.
