Driving home from work I saw this scene in front of me on the hill leading towards Hawi. It was such a striking example of the weather around here that I was moved to pull over and take a couple of photos.
The top photo shows the blue skies and scattered white clouds I’d been working under all day, and was standing under to take the photo. The gray band is wind-driven, low cloud being blown from east to west along the northern coast of the island, and blotting out the sun in this area. Under this band it was raining and visibility was poor. The cloud is channeled in this way by the northern shoulder of Kohala Mountain. As the band moved out over the ocean it became less pronounced as it dissipated.
Turning to my right, I took the bottom photo, a rainbow formed by the sun at my back and moisture tumbling over the mountain’s shoulder.
