Giant wave-like shelf cloud, seen near Sydney, Australia, during the Rolex Sydney Hobart Yacht race:
Some of these storm fronts will be classified as shelf clouds, but they still look like weird upside-down ocean waves. Here is the incredible supercell, which occurred in eastern Colorado on June 10th, 2006 (top image):
“And once the storm is over, you won’t remember how you made it through, how you managed to survive. You won’t even be sure, whether the storm is really over. But one thing is certain, when you come out of the storm, you won’t be the same person who walked in.”-- Good quote.
Shelf Cloud Unlike roll clouds, shelf clouds are attached to a larger parent cloud. But, like the roll cloud it, too, is an arcus cloud. They are often enormous and frequently forewarn the coming of a big storm, whereas roll clouds typically do not precede bad weather. Shelf clouds can falsely give the appearance of being a wall cloud (which comes after a storm) but a shelf cloud usually has a ragged bottom.
It's never too soon to start planning your next adventure...may we suggest the classic Sydney - Hobart Race, conducted around the Christmas holidays. It's a serious race with serious boats and serious danger...just the thing to make you feel totally alive moving into a new year....
