Ivan had already killed at least 70 people across the Caribbean before it hit the United States.

US authorities said the storm killed at least 14 people in northwest Florida, the so-called Florida Panhandle, including four who died when a tornado ripped into a mobile home park in Blountstown, 40 miles northeast of Panama City.

Six of the 13 were in the Pensacola region, which was worst hit by the storm which hit early Thursday.

Louisiana reported four hurricane-related deaths, Mississippi two, Georgia three and Alabama one, reports said. Six more people were killed in North Carolina in accidents such as falling trees as Ivan moved north, state emergency officials said.

There were widespread power outages in each state.
