New Mexico Summer Monsoon Season Precipitation Mapping
Updated: 09-30-2024
The maps below are focused on capturing unique elements of the summer monsoon season across New Mexico 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.

Total precipitation: Daily precipitation data summed from 6/15 to present. (Alternate color scale, Colorblind-friendly)
Percent of days with rain: A count of days observing greater than or equal to 0.01" of rain divided by the number of days between 6/15 and the current date. A value of 50% indicates that rain was observed on half of the days between 6/15 and the current date.
Max 1-day precipitation: This maps shows the single maximum 1-day precipitation amount observed in each data grid cell between 6/15 and the current date. (Colorblind-friendly)
Most Recent 24-hr Precipitation (ending 5am MST on date listed)
Percent of average precipitation: Percent of average is calculated by dividing the total accumulated precipitation by the long-term (1991-2020) mean and is an indication of how much totals have deviated from average precipitation for the June 15th to present period. 100% is equal to average for the time period shown on the map.
