On January 21st unusual clouds filled the sky. I had never seen anything like this before. Many coast residents photographed the event. These photos were taken by Don Spear,Pat Maxwell,  Michael Alexander and Shirley Mitchell respectively.

Here's what I wrote in my weekly column in the Independent Coast Observer:

Many people noticed the incredible clouds last Thursday. Justine Rosenthal’s class at Horicon School was amazed. One student said, “Look, we’re underwater!”

Michael Alexander saw them too. He wrote, “I looked up and saw these interesting cloud contours overhead. It looked almost like the surface of a very plush mattress.”

Pat Maxwell wrote, “The clouds were eerie and amazing. They reminded me of a Van Gogh painting. And for those of us who see faces in clouds, they were fascinating.”

Rick and I saw them over Gualala and we couldn’t believe our eyes. Shirley Mitchell was one of many to photograph the event. She wrote, “The clouds look like the ocean and/or sand dunes. I have never seen a sky like this. Wonders are always around us!”

Scott Gasparian knew what they were. He wrote, “They are pre-frontal strato-cumulus, with orographic forcing. In other words, the coast hills cause the waves. [There has] to be strong winds above the stratus layer to do that.”

It was an amazing sight to behold! Thanks to Pat, Don, Michael and Shirley for allowing me to share their photos with you here.

The wind has shifted this afternoon and the coast cooled off. Yesterday it was an unbelievable 81 degrees at our house. We may be headed back to winter soon, but no rain in this week's forecast.
