oCurrent Precipitation
US plots: Latest daily or 7 day total precipitation plots for the US. Included in US precipitation monitoring products. Stations used, archived recent plots and gridded data also available. NOAA CPC
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
