Original: Early on May 29, Tropical Depression One nearly attained tropical storm status, with intensity estimates using the Dvorak Technique reaching T2.5, or 40 mph (65 km/h); however, the estimates were also as low as T1.5, leading to the intensity of the depression remaining at 35 mph (55 km/h).
