NOAA's Climate Prediction Center (CPC) is monitoring the components of the hydrological cycle over North America using the Regional Climate Data Assimilation System (R-CDAS) which is the real-time continuation of the NCEP North American Regional Reanalysis (NARR). Details on the NARR can be found on the NARR website.
