US plots: Latest weekly, monthly, seasonal, and annual precipitation plots for the US. Total precipitation and percent of normal are available. Choose timescale from top of page. Then choose type of plot. NOAA CPC
Western US plots: Latest year-to-date interactive precipitation accumulation maps. Users can overlay topography, countiy boundries, climate division boundries, river and hydrologica boundries. line plots are aslo available. Select lat/lon bounds and optional overlay for maps. NOAA PSD
US plots: Latest 24 hourprecipitation plot. Plot over US plus other related data.UCAR RAP
Station Accumulation: 30 day accumulated precipitation for stations in the southwestern USChoose a station in the Southwestern US and obtain a plot of observed precipitation total for the last 30 days versus the historical average NOAA CPC
Regional Accumulation: Accumulated precipitation for gridded regions in the US from an input starting date in the last year. Click over a location and specify the starting time. You will get the accumulation over time versus the historical average NOAA PSD
River basins: Latest monthly precipitation totals for river basins in Colorado, New Mexico and Arizona.Text of accumulated precipitation and percent of normal for the different river basins of each state. Select month. Water year corresponds to the year of Sep in Oct-Sep. USDA NWCC
