(CNN) — Hurricane Dorian, the strongest storm ever to hit the Bahamas, has killed at least five people, pulverized houses and left countless residents homeless. As the storm lingers over the islands, forecasters predict it will move “dangerously close” to Florida later tonight, and millions of Americans are under mandatory evacuation orders.

Bahamian Prime Minister Hubert Minnis did not provide more details Monday about the people killed in the Abaco Islands. A woman earlier told a local news outlet that her 8-year-old grandson drowned in the rising waters.

“We are in the midst of a historic tragedy in parts of our northern Bahamas,” Minnis said at a news conference in Nassau.

Dorian made landfall as a Category 5 hurricane on Grand Bahama Island on Sunday night. Now a Category 4, Dorian has been crawling over the islands, and was stationary as of 7 p.m. That means it will pound the same decimated places over and over again.

Dorian was still an “extremely dangerous” storm with sustained winds of 120 mph on Tuesday, the National Hurricane Center said in its latest advisory.

The storm was 30 miles from Freeport, the main city on Grand Bahama on Monday evening. It is expected to slowly drift westward to northwestward overnight, and is then forecast to turn toward the northwest late Tuesday.

The storm wiped out power to Nassau and the rest of New Providence, the country’s most populous island, Bahamas Power and Light said.

“There’s damages everywhere around my area,” Marsh Habour resident Vernal Cooper said. “Cars and houses destroyed. This is what’s left of Marsh Harbour.”

“The initial reports from Abaco is that the devastation is unprecedented and extensive. They are deeply worrying. The images and videos we are seeing are heartbreaking,” Minnis said. “Many homes, businesses and other buildings have been completely or partially destroyed.”

Minnis said Coast Guard crews have rescued several injured residents in Abaco.The Coast Guard said more than 20 cutters were on standby in Key West, Florida for rescue operations in the Bahamas and the Caribbean.

“Bahamians across our country and throughout the world are praying for you,” Minnis said.

Storm expected to get “dangerously close” to Florida tonight

Dorian will keep lashing Grand Bahama Island though Monday night, forecasters said. It could dump a total of 24 to 30 inches of rain on northwestern parts of the Bahamas.

“It’s just an absolutely devastating, life-threatening situation,” said Ken Graham, director of the National Hurricane Center in Miami.

Then it’s expected to draw nearer to the southeastern US coast.

“The hurricane will then move dangerously close to the Florida east coast late tonight through Wednesday evening and then move dangerously close to the Georgia and South Carolina coasts on Wednesday night and Thursday,” the National Hurricane Center said.

“The very dangerous core of Dorian is expected to stay roughly 50 miles off the Florida coast, which will bring hurricane force winds, surge and heavy rain,” CNN meteorologist Dave Hennen said.

An 8-year-old boy is reported dead

Bahamian officials said it’s difficult to assess the number of casualties in part because conditions are still dire. “It’s not safe to go outdoors,” Bahamian Foreign Affairs Minister Darren Henfield said. “Power lines are down. Lamp posts are down. Trees are across the street. It is very dangerous to be outdoors.”

Ingrid McIntosh told Eyewitness News she believes her 8-year-old grandson drowned in the rising waters. Her 31-year-old daughter found the boy’s body, she told the local news outlet. She says her granddaughter is also missing.

“I just saw my grandson about two days ago,” McIntosh told Eyewitness News. “He told me he loved me. He was going back to Abaco, he turned around and said, ‘Grandma, I love you.'”

‘My house sounds like the ocean’

John Forbes, a resident of Grand Bahama, recorded video of the waters rising in his home. “Tragic flooding, we are stranded!” he wrote on Twitter. He later wrote that he was about to evacuate.

Vickareio Adderely’s home in Marsh Harbour is filled with water. One of the rooms is now “gone,” and a hole in the roof keeps getting bigger.

“My house sounds like the ocean,” Adderely said. “There are three houses adjacent to mine that also lost their roof.”

Kevin Tomlinson planned to ride out the storm in his home. But as Dorian’s strength became clear, he fled to an evacuation center in Freeport.

Tomlinson has no idea what will be left of his neighborhood when he goes home. “We haven’t really gotten the full brunt of it yet,” he said. “One thing I dread is the aftermath of this entire thing.”

How Dorian could pummel the US

After Dorian leaves the Bahamas, it threatens to turn its destructive force on the US Southeast. But it’s still unclear if or where the storm will make landfall.

Landfall happens when the center of the hurricane reaches land. Forecast models now show Dorian skirting along Florida’s coast Tuesday and then next to Georgia late Tuesday and Wednesday.

But just because the center of the storm might not hit land doesn’t mean it won’t be destructive. Hurricane-force winds topping 74 mph extend 45 miles out from the storm’s center.

The hurricane center said “life-threatening storm surges and dangerous hurricane-force winds are expected along portions of the Florida east coast through mid-week.”

The governors of Florida, Georgia and South Carolina ordered mandatory evacuations for some coastal residents.

More than 900 flights have been canceled going in and out of Florida airports, according to data from Flightaware.com.

SeaWorld Orlando announced the attraction would be closed on Tuesday because of the storm.

The Orlando Melbourne International Airport and Fort Lauderdale-Hollywood International Airport suspended commercial flights and closed terminals at noon Monday.

Even places as far north as North Carolina are potential targets for a US landfall, forecasters said.

In Wilmington, North Carolina, Christina Dowe said she bought a new home in November after her home was nearly destroyed by Hurricane Florence.

She said they were trying to get perishable, water and flashlights sot hey are better prepared than they were last year.

Dowe said she’s just hoping “everything works out better than it did last year.”

Gov. Roy Cooper told residents that preparations made now “could save your life later or lessen the chance that you might need rescue or shelter during the storm.”

“Time is running out to get ready,” he said.
