 Early on September 9, Luis turned towards the north and weakened to a Category 2 hurricane, with winds of 110 mph (165 km / h). Several hours later, the hurricane made its closest approach to Bermuda, passing about 200 mi (320 km) west of the island. Later that day, the storm began to accelerate as it traveled northeast ahead of a strong trough located to the northwest of Luis. During the afternoon of September 10, Hurricane Luis began to undergo an extratropical transition as it rapidly approached the Canadian coastline. Due to the rapid movement of the storm, significant weakening did not occur until Luis was at an unusually high latitude.
