HANOI (Reuters) -Storm Trami hit central Vietnam on Sunday, threatening to trigger heavy rains and dangerous floods after leaving a path of destruction in the Philippines. The storm hit the Philippines on Thursday, causing floods and landslides that have left 90 people dead as of Sunday, up from 46 deaths reported on Friday, the disaster agency said. Trami, with wind speeds of up to 88 kph (54.7 mph), made landfall in Hue and Danang. Maximum wind speeds have since weakened to 74 kph (46 mph). The storm has forced four airports in central Vietnam to temporarily close, according to the Civil Aviation Authority of Vietnam.
