Nicole heads up East Coast after 4 deaths in Florida

Officials in Volusia County declared that 49 beachfront buildings are “unsafe” and have ordered people to evacuate amid now-Tropical Storm Nicole.

“The structural damage along our coastline is unprecedented,” County Manager George Recktenwald said on the county’s website. “We have never experienced anything like this before, so we ask for your patience as we make our assessments. As always, the safety of our residents and visitors is our top priority. This is going to be a long road to recovery.”

Some of the impacted buildings are hotels and condos, officials said.

Four deaths have been tied to Tropical Storm Nicole, all in Florida's Orange County.

A man and a woman died after they were electrocuted by a downed power line on Thursday morning, the Orange County Sheriff’s Office said.

“We are urging all of our residents and visitors to use extreme caution if they are outside in the wake of the storm today,” the sheriff’s office said in a statement. “Never touch a downed power line. If you are driving and see a downed power line, change directions immediately.”

Two others died in a car crash on Florida's Turnpike in probable storm-related deaths, Orange County Mayor Jerry Demings said.

In Volusia County, Florida, damage along the coastline is “unprecedented,” according to county manager George Recktenwald.

No deaths have been reported in the county, Captain said. One person has been injured, he said.
