Average precipitation in March-April-May is lowest is the southwest and south central portion of the state, and it is here where the deficits (in terms of percent of normal) are the lowest in the state. La Niña events, and especially strong events, can result in meager amounts of spring precipitation. In Las Cruces, for example, spring precipitation was less than one tenth of an inch during four La Niña events (two strong events). 

 A description of the graphs is located at the bottom of the page.
