I hustled off the mountain (South Mt Ellen Summit, 11,400ft) because I saw this coming. When it hit it was drizzly at first, and I kept moving away from its dark core the best I could. But then suddenly another darker cloud came from the opposite direction and slammed hard with hail and flooding. When it hit I was in a perfect slickrock high spot with good drainage. So I called myself lucky, even though I got soaked. The next morning Mt Ellen was dappled with snow again.
El Niño is busy in South Utah, too!
