On the last day of the official hurricane season, Tropical Storm Otto formed in the north central part of the basin, about 800 miles east of Bermuda. It began several days ago as an upper Low which transitioned to a surface Low, gradually acquiring subtropical characteristics, and over the last couple of days acquired tropical characterisitics. i.e., relatively deep and persistent convection near the center of the circulation and a warm core aloft. This is the 15th named storm of the season. At 21Z today, Otto was located at 31.8N 51.0W and tracking N at 4kts. Satellite-estimated intensity is 40kts and 997mb. Over the next 2-3 days, the storm is forecast to drift to the east and slowly weaken in the face of increasing vertical wind shear.
