Tropical Depression One (2009)
On May 29, the depression almost became a tropical storm, when the storm's strength was measured at T2.5, or 40 mph (65 km/h) using the Dvorak technique. But some of the measurements were also low as T1.5, which was the reason why the NHC didn't call it a tropical storm. After a quick burst of convection during the night, thunderstorm clouds inside the depression started to disappear by 3:00 am EDT (0700 UTC). By then, the tropical depression was no longer expected to strength anymore and was forecasted to weaken. A few hours later, the center of circulation was ripped apart by strong wind shear while a nearby trough also started to absorb the rest of the storm. With no convection around the center of the storm, it became a remnant low during the afternoon. At 5:00 pm EDT (2100 UTC), the NHC gave out its last advisory on Tropical Depression One. The remains of the storm were later taken in by a warm front around 2 am EDT (0600 UTC).
