A turn toward the northwest is expected Saturday night or Sunday. Data from the aircraft indicate that maximum sustained winds have increased to near 105 mph (165 km/h) with higher gusts. Additional strengthening is forecast during the next 48 hours, and Matthew could become a major hurricane later today or tonight. Hurricane-force winds extend outward up to 45 miles (75 km) from the center and tropical-storm-force winds extend outward up to 185 miles (295 km). The latest minimum central pressure reported by the aircraft was 971 mb (28.67 inches).
