(2 Dec 2024) NCEP has scheduled an extended RRFS A outage for winter 2024-25. Data is expected to stop posting this week and resume by late winter or early spring.
The RRFS A is a prototype NOAA run and not for decision making. It will post as available, and outages may occur. More RRFS details are available here.
