Haiti ? Flooding from Tropical Storm Fay killed four people in Haiti and the Dominican Republic, and authorities said Saturday that the storm could reach hurricane strength as it barrels toward Cuba.

Florida’s Gov. Charlie Crist declared a state of emergency and said Fay threatened the state with a “major disaster.” Forecasters said Fay could bring hurricane-force winds to the Florida Keys as soon as Monday.

The U.S. National Hurricane Center in Miami said that late Saturday night the storm was about 175 miles (280 kilometers) southeast of Camaguey, Cuba. It was heading west at about 14 mph (22 kph), with maximum sustained winds of 45 mph (75 kph).
