Hurricane Beryl strengthened to Category 5 status late Monday after it ripped doors, windows and roofs off homes across the southeastern Caribbean with devastating winds and storm surge fueled by the Atlantic's record warmth.Beryl made landfall on the island of Carriacou in Grenada as the earliest Category 4 storm in the Atlantic, then late in the day the National Hurricane Center in Miami said its winds had increased to 160 mph (260 kph). Fluctuations in strength, and later a significant weakening, were forecast as the storm pushs further into the Caribbean in the coming days.
