President Trump says Florida will be ready for Dorian

President Donald Trump says Florida is "going to be totally ready" for Hurricane Dorian as it barrels toward the U.S. Southeast coast.

Trump says in an appearance on Brian Kilmeade's Fox News radio show that he spoke with Florida's Republican Gov. Ron DeSantis on Wednesday night and that, "He's all set."

He says: "We were ready in Puerto Rico and we're ready also in Florida."

Dorian is expected to grow into a potentially major Category 3 hurricane before it hits the U.S. mainland late Sunday or early Monday somewhere between the Florida Keys and southern Georgia.

Gov. DeSantis has declared a state of emergency for counties that could be in the storm's path and urged people to have a week's worth of supplies on hand.

Across much of Florida's east coast, residents are flocking to the grocery stores and gas stations, stocking up in anticipation of Hurricane Dorian, which threatens to hit over the Labor Day weekend.

There were lines at many gas stations in South Florida as people began filling gas cans and topping off their gas tanks.

Some residents using community Facebook groups provided updates on new shipments of water to restock the nearly empty shelves at local grocery stores.

Hurricane Dorian is posing an increasing menace to Florida as it pushes over open waters after doing limited damage in Puerto Rico and the Virgin Islands.

The U.S. National Hurricane Center says Dorian is expected to grow into a potentially devastating Category 4 hurricane before hitting the U.S. mainland late Sunday or early Monday somewhere between the Florida Keys and southern Georgia.

President Donald Trump tweeted a warning about the storm, adding that "it will be a very big Hurricane, perhaps one of the biggest!"

The Hurricane Center projects the storm could have winds of 125 mph (200 kph) by the time it reaches the mainland. Also imperiled are the Bahamas, with Dorian's forecast track running just to the north of Great Abaco and Grand Bahama islands.

Hurricane Dorian is moving over open waters after doing limited damage in Puerto Rico and the Virgin Islands, though forecasters warn it is gaining strength and probably will grow into a dangerous storm while heading toward Florida's east coast.
