Hurricane Dorian is likely to be packing a much bigger punch when it comes on shore this weekend. The storm is moving over open water after skirting Puerto Rico and sweeping over the U.S. Virgin Islands on Wednesday. The National Hurricane Center says Dorian's path over nothing but open water will build it up to a major Category 3 or Category 4 hurricane before it makes landfall late Sunday or early Monday. Forecasters say it's too early to know where the storm will come on shore. It could hit the mainland anywhere from Miami to south Georgia. A state of emergency has already been declared in Florida.
