(CNN) As of Thursday evening, Irma is still a Category 5 hurricane with winds of about 175 mph. Irma is one of three active hurricanes in the Atlantic basin right now. US warships are beginning Irma relief operations in the Caribbean.
-- Hurricane warnings are in effect for parts of Cuba, the Dominican Republic, Haiti, the Turks and Caicos Islands, and the southeastern, central and northwestern Bahamas.
-- Irma moved in on the Turks and Caicos. Storm surges could reach up to 20 feet, the National Hurricane Center says -- twice as high as some of the islands' elevations.
-- Irma could be near the central Bahamas on Friday. The Bahamas ordered evacuations for six southern islands:
-- Irma ravaged Barbuda, St. Martin and the British Virgin Islands
-- France's Prime Minister revised the death toll after the storm, saying four people died on St. Martin. One, an infant, died on Barbuda; there has also been one death reported on Anguilla and four in the US Virgin Islands.
-- Barbuda's Prime Minister says the island is barely habitable -- 95% of its buildings are damaged.
-- Puerto Rico was not directly impacted, but strong winds and torrential rains left hundreds of thousands without power and more than 56,000 without water.
-- In the Dominican Republic, at least 7,000 people have been displaced.
-- It is likely that Irma will make landfall in southern Florida as a dangerous hurricane, with Miami directly in its path. "Regardless of which (Florida) coast you live on, be prepared to evacuate," Gov. Rick Scott said.
-- Florida is under a state of emergency, with impact from Irma expected by late Saturday with potential landfall on Sunday.
-- The National Hurricane Center issued hurricane watches for these parts of Florida:
-- 31,000 people have evacuated the Florida keys. So far, officials labeled these counties as evacuation zones:
-- 12 shelters opened in Broward County. One of its smaller shelters, Pompano Beach High School, is full. They're directing residents in that area to Lyons Creek Middle School.
-- Florida's Emergency Information Hotline number: 1-800-342-3557.
-- 7,000 National Guard troops have been activated.
-- Florida Gov. Rick Scott is asking for 17,000 volunteers.
-- Georgia's governor declared a state of emergency for 30 counties that could be affected by the storm, and ordered evacuations in these areas (starting Saturday):
-- North Carolina and South Carolina are also getting ready. Both are under states of emergency
-- Hurricane Irma has maintained wind intensity above 185 mph longer than any other storm on record around the world -- a total of 37 hours.
-- The storm's cloud field is 300,000 square miles, which would cover the state of Texas.
This story has been updated to reflect a change in the death toll. The French government revised its count of the number of deaths attributed to Irma in the French Caribbean from eight to four.
