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.
