US_summary_May_precipitation_20240610-percent-normal.png

This map shows May 2024 precipitation (total rain and snow) received across the United States as percent of normal (1991-2020 average). Note that parts of the Southwest receive very little precipitation in May on average, so even a little less than usual precipitation can look like a severe deficit.
