Bahamas Prime Minister Hubert Minnis says his government has ordered a mandatory evacuation of islands in the southern part of the island chain because of Hurricane Irma.
Minnis says the Category 5 storm poses a dire threat to the islands of Mayaguana, Inagua, Crooked Island, Acklins, Long Cay and Ragged Island.
People who live on the islands will be flown Wednesday to Nassau on the island of New Providence. Minnis says it will be the largest hurricane evacuation in the history of the Bahamas.
People who don't evacuate will be at "great danger" from storm surge caused by what he called a "monster" hurricane. Minnis says emergency personnel may not be available to rescue them when the storm is at its height between Thursday and Friday.

Puerto Rico's governor is warning that the effects of Hurricane Irma could be catastrophic, calling the storm more dangerous even than Hurricane Harvey, which recently devastated Houston.
Gov. Ricardo Rossello said Tuesday that the "dangerousness of this system" has never been seen in Puerto Rico.
In his words: "It is much more dangerous than Harvey. The results could be catastrophic and devastating."
Rossello says the winds of the Category 5 storm will lash Culebra island around dawn Wednesday and move to Puerto Rico shortly afterward. He says the U.S. territory's northeast coast will feel the brunt.

The U.S. Army Corps of Engineers is releasing water from Florida's Lake Okeechobee in preparation for Hurricane Irma's expected arrival in the state this weekend.
Spokesman John Campbell said Tuesday the plan is to drain the lake for three days to drop its current level of almost 14 feet.
The corps says Irma could add a foot of water directly to the lake as it passes and then 3 feet of runoff in the coming weeks. The corps tries to keep the lake below 16 feet and worries about the stability of the Hoover Dike, which surrounds the lake, if it exceeds 18 feet.
Most of current dike was built in the 1960s. It averages 30 feet in height. Failures of the original embankments during hurricanes in 1926 and 1928 killed over 3,000 people when waters flooded neighboring towns. About 40,000 people live nearby today.
The dike has been undergoing a $1.7 billion improvement plan that should be finished in the mid-2020s.

People in the Florida Keys are putting up hurricane shutters and wooden boards on homes and businesses as powerful Hurricane Irma approaches the Caribbean on a path that could take it to the U.S. by the weekend.

Theresa Webster, 60, of Fort Lauderdale had heard water was sold out at Publix but still available at Winn Dixie, but there was none by the time she got there in the afternoon.
She was also stocking up on canned tuna, crackers and bread.

Hurricane Irma is the most powerful storm ever recorded in the Atlantic Ocean.
The U.S. National Hurricane Center says the Category 5 storm has winds of up to 185 mph (297 kph) as it approaches the Leeward Islands of the northeast Caribbean.
Four other storms have had winds that strong in the overall Atlantic region, but they have been in the Caribbean Sea or the Gulf of Mexico where the usually warmer waters fuel tropical cyclones.
Hurricane Allen hit 190 mph in 1980, while 2005's Wilma, 1988's Gilbert and a 1935 great Florida Key storm all had 185 mph winds.
Experts say Irma's strength is a result of unusually warm water for that part of the Atlantic.
