La Niña events impact the winter precipitation across southern New Mexico to a greater degree than other areas in the state. All three stations examined in this area reported DJF precipitation of 67% to 75% of the long term normal DJF. The reduction of precipitation is even more dramatic in strong La Niña events, especially in Fort Sumner.
