By Spring, the effect of La Niña in the southwestern mountain increases, and the average deficits in precipitation increase, particularly at Grants. In strong La Niña events, deficits average less than 50% of the long term normal.

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

winter precip for grants during la nina events

Percent of Longterm Average for all La Niña Events = 62% , for strong La Niña Events = 46%

winter precip for luna during la nina events

Percent of Longterm Average for all La Niña Events = 64% , for strong La Niña Events = 44%

Precipitation values for 3-month periods during 19 La Niña Events since 1949-50 are plotted with respect to the long term precipitation average, listed to the right of the graph. The precipitation totals for each 3-month period are plotted above or below each bar. Years for which the La Niña Event was considered to be strong are colored in purple. "M" represents a 3-month period with missing data. Finally, the percents of longterm normal for all La Niña events and for the strong La Niña events are listed below each graph.
