TAMPA, Fla. (Reuters) – Hurricane Hermine tore a path of destruction across Florida on Friday, knocking out power for 253,000 customers, flooding low-lying areas and raising concerns about the spread of the Zika virus from pools of standing water left behind.

The first hurricane to make landfall in Florida in more than a decade, Hermine came ashore early on Friday near St. Marks, Florida, 20 miles (30 km) south of the capital of Tallahassee, packing winds of 80 mph (130 kph) and churning up a devastating storm surge in coastal areas.

Hermine, which has since been downgraded to a tropical storm, was set to snarl U.S. Labor Day holiday travel as it moves northeast after battering Florida’s $89 billion tourism industry.

The storm center was on the border between Georgia and South Carolina at 2 p.m.(1800 GMT), the National Hurricane Center (NHC) said.

Though sustained winds had weakened to 50 mph (80 kph), the tempest headed toward the Atlantic seaboard on a path where tens of millions of Americans live, causing storm watches and warnings stretching to Rhode Island, NHC said.

It could strengthen again over water and possibly bring up to 15 inches (38 cm) of rain to the southeastern and mid-Atlantic states over the next 48 hours, with heavy rainfall possibly hitting coastal Delaware and New Jersey starting on Saturday night, the center said.

New Jersey, still mindful of the devastation caused by Hurricane Sandy in 2012, was on high alert as emergency officials advised people to prepare for flooding, high winds and a surge of seawater.

New York Governor Andrew Cuomo on Friday activated his state’s emergency operations center and advised emergency officials to stockpile resources, including sandbags and generators.

As it tracks north offshore towards New York, the storm is projected to stall at sea through Wednesday morning, the National Hurricane Center said.

New York Mayor Bill De Blasio said residents should avoid beach waters for fear of life-threatening riptides caused by the lingering storm. “I say that to people who go the beach, I say that to surfers: Don’t even think about it,” De Blasio told a news conference.

WORRIES ABOUT ZIKA

In Florida, concerns over the standing water in which mosquitoes breed intensified as the state battles an outbreak of the Zika virus.

“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, also warning people to look for downed power lines and avoid driving in standing water pools.

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. Active transmission is thought to be occurring in two small areas around Miami.

As the sun rose on Friday morning on Hudson Beach, just north of Tampa, cars sat askew in flooded roads. Palm fronds, tree branches and garbage cans were scattered about.

Overnight, Pasco County crews rescued more than a dozen people after their homes were flooded.

Richard Jewett, 68, was rescued from his home in New Port Richey, just north of Tampa, around 1:30 a.m. EDT (0530 GMT) as emergency workers carried out a mandatory evacuation.

“The canal started creeping up toward the house and even though it wasn’t high tide it looked like it was coming inside,” Jewett said.

In Cedar Key, an island community in northwest Florida, waters rose more than 9.5 feet (2.9 meters), among the highest surges ever seen, the National Weather Service said.

“This is one of the worst that we have seen in the city in a long time, and unfortunately, it is not over yet,” St. Petersburg, Florida, Mayor Rick Kriseman told reporters.
