Florida coast battered by Hurricane Hermine

The first hurricane to hit Florida in a decade has killed one person, caused severe damage and knocked out power to nearly 300,000 homes and businesses.

Now downgraded to a tropical storm, it is pushing north-eastward. Emergencies have been declared in Georgia, North Carolina, Maryland and Virginia.

A state of emergency remains in effect for most of Florida.

There are concerns over stagnant water in the state, which has been battling the mosquito-born Zika virus.

Gusts of 80mph (130km/h) caused storm surges that flooded part of the Florida coast.

In the town of Cedar Key, waters rose more than 9.5ft (2.9 metres), among the highest surges ever seen, according to the National Weather Service.

A 56-year-old man died when a tree fell on the tent he was sleeping in, local media reported.

After making landfall early on Friday, Hermine swept through Florida and Georgia.

Having weakened to a tropical storm, it entered South Carolina, where local officials have reported flooded roads, fallen trees and power outages.

But the National Hurricane Center predicted it would regain hurricane strength after emerging into the Atlantic Ocean, and a tropical storm warning was issued for parts of New Jersey, Connecticut and New York City.

It is expected the storm conditions will reach New York on Sunday.

The US Coast Guard also warned boaters and swimmers along the New York and New Jersey coasts to use caution in what is expected to be rough surf and hazardous rip currents this weekend.

Zika fears

There are also fears that the stagnant water caused by the storm surge in Florida could provide a breeding ground for mosquitoes.

There have been 47 cases of Zika in people believed to have contracted the virus through local mosquitoes, according to the Florida Department of Health.

"It is incredibly important that everyone does their part to combat the Zika virus by dumping standing water, no matter how small," Florida Governor Rick Scott told a news conference on Friday.

Police in Taylor County, Florida, that has a population of more than 20,000, said the storm had inflicted "severe damage".

In the state capital Tallahassee, at least 70,000 homes were without power at one point, affecting 60% of people in the region.

In Georgia, Governor Nathan Deal also declared a state of emergency, for 56 counties, but the state was spared the havoc it had expected.

"We're having a bit of a sigh of relief," said Jim Butterworth, director of the Georgia Emergency Management Agency.

But 107,000 customers were reported to be without power across the state as crews worked to repair damage.

Category one: sustained winds of 74-95mph (119-153 km/h); some damage and power cuts

Category two: winds of 96-110mph (154-177 km/h); extensive damage

Category three: winds of 111-129mph (178-208 km/h); well-built homes suffer major damage

Category four: winds of 130-156mph (209-251 km/h); severe damage to well-built homes, most trees snapped or uprooted

Category five: winds of 157 mph (252 km/h) or higher; high percentage of homes destroyed, area uninhabitable for weeks or months
