Carlos lost its brief hurricane status early yesterday then picked up some strength. By late afternoon, the storm's centre was 75 miles (120 kilometres) west-southwest of Acapulco and had top sustained winds of 70 mph (110 kph), the US National Hurricane Center said. The former Category 1 hurricane was moving northwest about 3 mph (5 kph) and was forecast to become a hurricane again during the night.
Beaches along the iconic Acapulco Bay, normally filled with families on a weekend afternoon, were nearly deserted as waves nearly 6 feet (2 meters) high broke against the shore, washing away 16 small palm-frond huts.
Sergio Pina, a business risk manager from Mexico City, stood among a group of spectators watching the wild weather. "It's impressive. It's very strong," he said. "There are launches turned over, fallen cables."
