More information is available from NOAA's Climate Prediction Center. El NiГ±o conditions could impact temperature and precipitation patterns across the United States. El NiГ±o still probable later this year: According to NOAA's Climate Prediction Center, there is a 2-in-3 chance of at least a weak El NiГ±o developing during the next 1-2 months and lasting into spring 2015.More information is available from the U.S. The long-term drought conditions across the region will continue to impact water resources and agriculture and increase wildfire risk. Along the Pacific Coast, precipitation was insufficient to significantly improve drought conditions, with drought still impacting all of California.
