CNN  — 

At least two people have died during the damage wrought by Nicole’s overnight landfall Thursday along Florida’s eastern shore, which knocked out power to thousands, pushed buildings near collapse and flooded the coast as the first hurricane to hit the United States in November in nearly 40 years.

Two people were “electrocuted by a downed power line” in Orange County, the Orange County Sheriff’s Office said in a press release.

A tornado threat, plus powerful wind and heavy rain, are expected to continue Thursday in parts of Florida, Georgia and South Carolina after Nicole, which hit at Category 1 strength, weakened to a tropical depression. All tropical storm and storm surge warnings have however been discontinued.

Meanwhile, communities are assessing the damage.

At least 49 beachfront buildings including 24 hotels and condos have been deemed “unsafe” following Hurricane Nicole in Volusia County, officials said in a press release. “The structural damage along our coastline is unprecedented,” county manager George Recktenwald said in the release. “We have never experienced anything like this before, so we ask for your patience as we make our assessments.

An additional 11 structures on Daytona Beach shores have already been deemed compromised, according to Recktenwald.

Volusia County officials have “declared a curfew in incorporated and unincorporated areas east of the Intracoastal Waterway from 11:22 a.m. Thursday, Nov. 10, through 7 a.m. Friday, Nov. 11,” said a Volusia County storm update.

Two hundred residents were housed in county shelters, said the update. Three shelters remain open. Roughly 23,000 customers are without power in the county, according to PowerOutage.us.

In Indian River County, officials Thursday morning will “be assessing debris and messaging cleanup plans,” said spokesperson Kathy Copeland. In St. Lucie County, there were so far “no serious reports of damages or injuries,” spokesperson Erick Gill said, adding, “Most likely the biggest impact is going to be beach erosion.”

At 10 p.m. ET Thursday, Nicole was packing 35-mph sustained winds and centered about 20 miles north of Tallahassee, moving northwest at 15 mph.

Up to 8 inches of rain could drench eastern, central and northern portions of Florida through Saturday. And between 2 to 6 inches are expected from parts of the US southeast to the southern and central Appalachians and western mid-Atlantic, the hurricane center said.

Nicole weakened to a tropical storm shortly after landfall, and then became a depression late Thursday. It’s expected to become a post-tropical cyclone over the Southeast.

Here’s what to know now:

Residents outside Florida should now prepare: There are nearly three million people under a tornado watch issued for southeast Georgia, eastern and southern South Carolina and portions of far southern North Carolina. “Given the uncertainty of the storm’s strength and path as it approaches South Carolina, residents need to have their personal emergency plans ready to go just in case we need to take safety precautions later in the week,” said Kim Stenson, who heads the state’s emergency management division.

Tens of thousands without power: More than 237,000 homes and businesses in Florida were without power late Thursday, according to PowerOutage.us.

Low tide limits storm surge: Nicole’s peak winds coincided with low tide, limiting the storm surge and inundation on the shore. At Port Canaveral, the surge was measured at just under 6 feet around 4 a.m. ET, just after landfall. Later Thursday morning, surge was down to around 3 feet, but water levels are expected to remain high through high tide, between 8 a.m. and 10 a.m.

Nicole's storm surge pushes Wednesday into East Boynton Beach in Florida.

King Tide puts structures at risk: The King Tide that affected Volusia County Thursday morning “is of great concern for potentially further damage to structures,” said officials with Volusia County Emergency Management. King Tides is a term used to describe higher than normal tidal cycles that typically occur during a new moon or a full moon when the moon makes its closest pass to the Earth. When they coincide with bad weather including heavy rain, winds and waves, they can cause severe flooding. Because of rising sea levels, King Tides are becoming more frequent and severe.

Flights canceled and schools closed: The storm’s colossal path led to the closure of many schools, colleges and universities, as well as the cancellation of hundreds of flights and the shuttering of amusement parks. Orlando International Airport halted operations Wednesday afternoon, and Miami International Airport warned of cancellations but did not plan to close.

Historic hurricane: Nicole’s landfall Thursday was the latest in a calendar year a hurricane has ever struck Florida’s Atlantic coast. It broke the record set by the Yankee Hurricane, which hit Florida’s east coast on November 4, 1935.

Where the storm hit: The storm struck just south of Vero Beach with winds of 75 mph before quickly weakening, the National Hurricane Center said. Its strong winds, downpours and storm surge thrashed some areas hit in September by Hurricane Ian. Nicole on Wednesday brought strong winds and dangerous storm surge to the northwestern Bahamas.
