 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 .
