Wildfire Risks

Wildfire risk is mostly normal for the continental U.S. However, long term drought coupled with increasing potential for offshore winds will keep potential elevated in California through October. >>Click for more information on US Wildfire

Mapping El Niño's effect on the frequency of climate risks 

NOAA's Dr. Klaus Wolter has led an update to the "Risk of Seasonal Climate Extremes in the U.S. Related to ENSO" (El Niño/Southern Oscillation). The updated maps show regions with increased or decreased risk of extreme warm/cold (or dry/wet) seasons during an ENSO event.

What does El Niño mean, really? 

Simply put, El Niño is a warming of the ocean surface, or above-average sea surface temperatures (SST), in the central and eastern tropical Pacific Ocean. And it has potential implications for weather in the Western Hemisphere. What does that mean for you? NOAA's Climate.gov hosts a blog exploring the phenomenon.
