El Niño is a phenomenon of the ocean-atmosphere system in the tropical Pacific. It displaces a huge volume of warm water from the western Pacific, moving it to the eastern Pacific. This disruption has important consequences for weather and climate around the globe.

El Niño is not a single storm like Hurricane Katrina. Nor is it a single tornado or severe thunderstorm. We cannot say that a single storm is El Niño. Rather, we might see a series of storms over a period of days producing above normal rainfall totals.

As part of KTLA’s El Niño coverage for 2015 and 2016, we’ve put together this comprehensive guide:

  1. Defining El Niño
  2. El Niño and Southern California Weather
  3. Impacts From El Niño
  4. What Can We Expect?
  5. Distinguishing Normal Weather From El Niño-Driven Storm Patterns
  6. Getting Weather Information, More Resources, Links
