Hurricane Milton updates: 16 dead across Florida in storm's aftermath

Palm Beach County Sheriff Ric Bradshaw said damage to the Wellington area from a suspected tornado on Wednesday was extensive.

Bradshaw told reporters during a press briefing Thursday that he flew in a helicopter to survey the damage from the air.

"When you see the devastation from the air, it's amazing, it looks like a war zone," he said.

The sheriff said damage assessments of about 200 homes showed most were uninhabitable.

"I can tell you why: The places I saw looked like it was an atomic bomb that blew it up," Bradshaw said.

Bradshaw said crews are doing more searches with drones now.

Seven people were injured in the storm, officials said.

Storm surge and tropical storm warnings for Milton have been discontinued, as the storm is racing out to sea.

Four people died in Volusia County, on Florida's east coast, in connection with Milton, the local sheriff said.

Two died due to fallen trees, according to Volusia County Sheriff Michael Chitwood.

A third person died from a heart attack while boarding up property, while another went into cardiac arrest and first responders couldn't get there in time during the storm, the sheriff said.

Flooding continues to be a risk in the county, local officials said, while urging people to stay off the roads. A curfew is in place from 9 p.m. Thursday to 5 a.m. Friday.

President Joe Biden called on Congress to return to Washington “immediately” to pass additional funding for disaster aid, warning that the Small Business Administration is close to exhausting funds for disaster loans.

“I think Congress should move as rapidly as they can, particularly on the most immediate need, which is small business,” he said.

Biden said they should also quickly move to approve additional funds for FEMA.

The president warned that anyone who tries to take advantage of Americans through price gouging or scams will be held accountable.
