HURRICANE Matthew has left 1.4million Americans without power as the death toll in Haiti approaches 900.

The storm has now been downgraded to a category one as it moves through South Carolina.

Tides of up to 9ft buffeted the city of Charleston as sea water made it over the sea defences and flooded the historic area with ten inches of water.

Incredible images showed locals wading through the water that has inundated the port city.

Millions along the coast of Florida, Georgia and South Carolina now face a long wait to have their power switched back on.

Six Americans were killed during the ferocious storms.

But tiny Haiti bore the brunt of the tragedy as it announced the deaths of almost 900 people on today.

The impoverished country is expecting to see that number rise further still.

Up to 90 per cent of the worst-affected areas have been destroyed.

Aerial pictures of Haiti show a picture of devastation as rescuers struggle to reach isolated villages.

The UN said it expected the number of dead to rise even further.

Around 350,000 people are in desperate need of emergency aid, it warned.

And terrifying footage showed the power of storm surges that experts fear could threaten the Carolinas until tonight.

One home was buffeted by the powerful waves as they crashed into the patio doors.

Florida breathed a sigh of relief yesterday as much of the state avoided serious damage.

Matthew stalked the eastern coast for much of the day, eventually making landfall near the Cape Canaveral space port.

More than 4,500 flights have been cancelled so far between Wednesday and Saturday, and major tourist attractions in Florida have been shut down.

Disney World was amongst those - closing its door for the first time in 11 years.

Power was cut off for more than 600,000 in Florida and Georgia overnight.

President Barack Obama called for those staying in their property to heed the warnings of local officials.

He said: "This is still a really dangerous hurricane, that the potential for storm surge, flooding, loss of life and severe property damage continues to exist.

“Do not be a holdout here, because we can always replace property but we can’t replace lives."

Earlier yesterday, some Floridians had expressed regrets at not fleeing before the "terrifying" storm hit.
