Cyclone Yasi, a category 5 storm is expected to make landfall in Australia at midnight local time. The damage could be significant especially when you consider how large this cyclone is. My buddy at Barclays shared this map with me to give you a size of the cyclone. This satellite image shows the cyclone transposed over the map of the U.S. If the damage is significant, it could take the Australian dollar back below parity.
