At 7 a.m. CDT, the center of Hurricane Delta was located about 160 miles (255 km) south of Cameron, LA. Delta is moving toward the north near 12 mph (19 km/h), and this motion is expected to continue today followed by a north-northeastward motion by tonight. On the forecast track, the center of Delta will move inland within the hurricane warning area this evening.

Maximum sustained winds are near 120 mph (195 km/h) with higher gusts – a category 3 hurricane on the Saffir-Simpson Hurricane Wind Scale. Hurricane-force winds extend outward up to 40 miles (65 km) from the center and tropical-storm-force winds extend outward up to 160 miles (260 km). Slow weakening is expected to begin as Delta approaches the northern Gulf coast later today, with rapid weakening expected after the center moves inland.

For today through Saturday, Delta is expected to produce 5 to 10 inches of rain, with isolated maximum totals of 15 inches, from southwest into central Louisiana. These rainfall amounts will lead to significant flash, urban, small stream flooding, along with minor to major river flooding. For extreme east Texas into northern Louisiana, southern Arkansas, and western Mississippi, Delta is expected to produce 3 to 6 inches of rain, with isolated maximum totals of 10 inches. These rainfall amounts will lead to flash, urban, small stream, and isolated minor river flooding.

The next complete advisory will be issued by NHC at 10 a.m. CDT – www.hurricanes.gov
