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.
