Although U.S. news media have reported that Hurricane Irma has been inflicting damage on the north shore of Cuba, they generally have not provided details, probably because they do not have reporters on the island.
However, early on September 10, Reuters reported that Irma uprooted trees and tore off roofs in Cuba . . . with 125-mile-per-hour (200-km per hour) winds that damaged hotels in the island’s best-known beach resorts and forced evacuations as far along the coast as low-lying areas of the capital Havana. Power was out and cellphone service was spotty in many regions as Irma neared the end of a 200-mile (320-km) trek westwards” on the north shore of the island. The hurricane was forecast to leave Cuba about 150 miles (240 km) east of Havana and head north toward Florida “late Saturday.”
Associated Press, also early on September 10, added that “authorities on the island were assessing the damage and warning of staggering damage to keys off the northern coast studded with all-inclusive resorts and cities, as well as farmland in central Cuba.” In addition, late Saturday these authorities warned that flooding had reached more than 2,000 feet (600 meters) into Havana and was going to last more than 36 hours. There have been no immediate reports of deaths caused by the hurricane.
Nick Miroff of the Washington Post on Saturday afternoon reported that the hurricane had been “swamping seaside towns and shredding the island’s rickety infrastructure, though there were no reports of deaths or injuries.” He had seen images of “downed trees and rubble-clogged streets” and “power lines and electrical posts . . . strewn across roads and highways.” Some towns “reported damage to 60 percent of homes, as the storm shredded zinc roofing panels and blasted apart old Spanish tiles.” 
The Miami Herald had a similar report early on September 10 with images of damage. It said there were reports of “heavy flooding” from Matanzas to Havana with “waves between 19 and 30 feet.”
