The Climate Prediction Center (CPC) produces maps of the United States that show probability of precipitation and
temperature being above or below normal based on data from previous El Niño Southern
Oscillation (ENSO) events.

- Previous ENSO Events - Previous El Niño and La Niña years and intensity of event.

- El Niño
Impacts on U.S. Climate - Maps for the lower 48-states provide insight into the likelihood of extremes of
temperature and precipitation during El Nino events.
- El
Niño Impacts State by State - State-specific maps by climate division compare temperature and precipitation
conditions during strong El Niño years with normal conditions. Bar graphs show the
likelihood of extremes of temperature and precipitation.
- La Niña
Impacts by Region - Pie charts provide temperature and precipitation probabilities for being above or below
average during La Niña years for climate regions in the lower 48-states. Bar charts
provide maximum, minimum, and average temperature and precipitation.
- El
Niño's Influence on U.S. Precipitation Amounts - A series of maps depict United States lower 48-state's precipitation for the
November-March periods for non-El Niño years, El Niño years, and the very strong 1982/83
El Niño by number of days and percentage of days in a specific range from 0.01 inches to
greater than 1.0 inches.
- El
Niño, La Niña, Neutral - Snowfall for Selected Cities - Bar graphs depict mean snowfall for selected U.S. cities in El Niño, La Niña and
neutral years.
