(Reuters) - About 600,000 Florida homes were without power on Friday due to Hurricane Matthew and more outages were likely, Governor Rick Scott told a news conference, as the storm moved near the state's Atlantic coast on a northward track after killing hundreds of people in Haiti.

"We're going to have more outages," Scott said, adding that there was a potential for significant flooding from the hurricane in the Jacksonville area. "The worst part of this is still to come. ... We still have potential for a direct hit and we're seeing 100-mile-per-hour winds."
