NOAA: Meet RAP (Rapid Refresh)

Save pagePDF pageEmail pagePrint page

RAP or Rapid Refresh offers:

An operational NOAA/ NCEP hourly updating operational weather prediction system covering North America comprised primarily of:

  • A numerical forecast model
  • An analysis/assimilation system to initialize that model.

These hour to hour updates can help us see weather models updated faster, more accurately, and provide valuable information for severe weather warnings.

The Rapid Refresh replaced the RUC as the NOAA next-generation hourly-updated assimilation/modeling system operational at NCEP at 12z on 1 May 2012.
