At 7 a.m. CDT, the center of Hurricane Delta was located over the Gulf of Mexico about 425 miles (685 km) south of Cameron, Louisiana. Delta is moving toward the northwest near 15 mph (24 km/h), and this motion with a reduction in forward speed is expected today. On the forecast track, the center of Delta will move over the central Gulf of Mexico today, and move inland within the hurricane warning area Friday afternoon or Friday night.
Reports from the Hurricane Hunter aircraft indicate that maximum sustained winds are near 100 mph (155 km/h) with higher gusts – a category 2 hurricane on the Saffir-Simpson Hurricane Wind Scale. Hurricane-force winds extend outward up to 35 miles (55 km) from the center and tropical-storm-force winds extend outward up to 125 miles (205 km). Strengthening is forecast to occur, and Delta is expected to become a major hurricane again by tonight. Some weakening is forecast when Delta approaches the northern Gulf coast on Friday.
