Hurricane Matthew, the first fiercest hurricane in more than 10 years, is on its deadly destructive march towards the southeastern United States after killing at least 339 people in Haiti.

Matthew, which is carrying dangerous winds of 140 mph (220 kph), is moving dangerously close to the Florida First Coast and Southeast Georgia Coast.

"Matthew has re-strengthened to a Category 4 hurricane prior to brushing the east coast of Florida early Friday morning," AccuWeather hurricane expert Dan Kottlowski explained.

On Thursday, US President Barack Obama declared a state of emergency in Florida and Georgia. Millions in the southeastern United States were asked to head for safety. Gov. Rick Scott said that the state could be facing its "biggest evacuation ever" as the hurricane approaches.

"We have nothing left to survive on, all the crops have gone, all fruit trees are down, I don't have a clue how this is going to be fixed," said Marc Soniel Noel, deputy mayor of Chantal.
