DISCUSSION AND OUTLOOK ---------------------- At 700 AM CDT (1200 UTC), the center of Tropical Storm Barry was located near latitude 31.4 North, longitude 93.4 West. Barry is moving toward the north near 6 mph (10 km/h), and this general motion is expected to continue through Monday. On the forecast track, the center of Barry will move across the western and northern portions of Louisiana today, and over Arkansas tonight and Monday. NOAA Doppler weather radar data and surface observations indicate that maximum sustained winds remain near 45 mph (75 km/h) with higher gusts. These winds are occurring near the coast to the southeast of the center. Weakening is expected as the center moves farther inland, and Barry is forecast to weaken to a tropical depression later today. Tropical-storm-force winds extend outward up to 175 miles (280 km) mainly over water to the southeast of the center. A sustained wind of 39 mph (63 km/h) was recently reported at Cypremort Point, Louisiana, located in Vermilion Bay. The estimated minimum central pressure based on surface observations is 1005 mb (29.68 inches).

The water could reach the following heights above ground somewhere in the indicated areas if the peak surge occurs at the time of high tide... Intracoastal City to the Mouth of the Atchafalaya River...1 to 3 ft Mouth of the Atchafalaya River to Biloxi MS, including Lake Pontchartrain...Water levels are decreasing to normal levels as the storm moves inland.
