Post-tropical cyclone Arthur, downgraded from a hurricane, left hundreds of thousands of people from New England to Canada without power Saturday as it traveled up the Atlantic coast. Heavy rain pounded parts of New Brunswick and Nova Scotia as parts of New England dealt with dangerous flooding. But business owners in North Carolina are breathing a sigh of relief that things weren't worse. Meanwhile, officials along the Northeast coastline are warning beach goers of potentially dangerous rip currents that could rock the waters in Arthur’s aftermath. So far, no deaths or injuries associated with Arthur have been reported.
