Status of California Storm as of 7am

Power Outages
More than 530,000 homes and businesses without power meaning more than 1.6 million people are without power.

  • Magenta (LA area) = flash flood warning. 
  • Bright green = flood warning
  • Green = flood watch 
  • Pink = winter storm warning. 
  • Amber = high wind warning. 
  • Sand = wind advisory (lesser condition)
  • Purple = winter weather advisory

The purple is an extreme risk. The red is a high risk. 


  1. This is an interesting pattern, very similar wo what we experience near Lake Michigan. When we get low level flow across the lake, it many times according to conditions, it produces either rain or snow bands. It is just very intriguing that this is happening at a much larger scale.

    1. Hi Richard, thank you for the comment. However, the lake effect snows are due to the water of the Great Lakes being significantly warmer than air temperatures. That is not a factor in this type of (El Nino-driven) storm. Thanks for reading!
