Florida coast battered by Hurricane Hermine
Video
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.
