The maps below are focused on capturing unique elements of the summer monsoon season across Arizona including total precipitation, intensity, and frequency of precipitation events. Maps are updated once a day from June 15 - September 30th using gridded precipitation data (nominally 4km by 4km) provided by the NOAA National Water Prediction Service. The gridded data provide a spatial estimate of true precipitation amounts across the region and should be interpreted with caution at very fine scales. Note that radar coverage is limited across the Four Corners and precipitation amounts will be underestimated across this region. More information on how the gridded data are produced can be found here.
