Official Advisory Discussion

At 1000 PM CDT (0300 UTC), the center of Post-Tropical Cyclone Arthur was located near latitude 29.7 North, longitude 94.5 West. The post-tropical cyclone is moving toward the northeast near 9 mph (15 km/h). A northeastward motion at a faster forward speed is expected tonight, followed by a turn toward the east-northeast Thursday through Friday. On the forecast track, the remnants of Arthur should move farther inland over southeastern Texas and western Louisiana tonight, then cross the southeastern United States Thursday through Friday.

Maximum sustained winds are near 35 mph (55 km/h) with higher gusts. While additional weakening is expected as the system moves inland, the remnants of Arthur will continue to produce widespread heavy rains across the southeastern United States during the next few days.

The estimated minimum central pressure based on surface observations is 1000 mb (29.53 inches).
