Government forecasters say while they except El Niño to remain weak, there’s a 50-60 percent chance that it could last into the summer.
NOAA scientists say a weak El Niño typically has no widespread or significant global impacts, but say some places in the Northern Hemisphere could see localized affects.
During El Niño episodes, the storm track across the United States tends to shift south during the spring and summer, bringing the chance for increased precipitation to much of the west.
In Colorado, conditions tend to be wetter and warmer-than-average.

While conditions have improved significantly since mid-February, especially in the southern river basins, we’re still running a bit behind where we should be.
