Hurricane Gustav gaining strength south of Haiti

PORT-AU-PRINCE, Haiti (AP) -- Hurricane Gustav is growing rapidly as it closes in on impoverished Haiti.

At 11 a.m. Eastern time, the center of Gustav was located about 50 miles south of Port-au-Prince. It's moving toward the northwest near 9 miles-an-hour, and is packing top sustained winds near 90 miles-an-hour.

At the Port-au-Prince airport, stranded travelers mobbed the American Airlines counter, desperate to rebook tickets after the airline canceled all flights.

The storm is on track to slice along the south coast of Cuba during the week before entering the Gulf of Mexico on Sunday.

Fears that Gustav could disrupt oil drilling operations in the Gulf have sent global oil prices soaring.
