River Basin Real-time Rainfall and 1-day to 2-week Forecasts 

These interactive maps displays 1- and 5-day 00Z accumulated satellite-based rainfall estimates and precipitation forecasts for each watershed.  The satellite precipitation is a merged product of NASA TRMM, NOAA CMORPH, and JAXA GSMaP precipitation and is provided immediately after the 24-hr accumulation period is complete.  Rainfall forecasts are derived from NCEP, Canada Meteorological Centre, ECMWF, and the UKMet Office, with predictions providing the ensemble minimum, mean, and maximum values of each weather forecast center.
