After peak intensity, Nadine began weakening once again and deteriorated to a tropical storm at 1200 UTC, on October 1.[1] Northwesterly winds began to increase on October 3, after an upper-level trough that was causing low wind shear moved eastward.[31] A few hours later, the low-level center became partially exposed,[32] before becoming fully separated from the convection by 1500 UTC.[32] Due to strong wind shear and cold sea surface temperatures, showers and thunderstorms rapidly diminished, and by late on October 3, Nadine became devoid of any deep convection.[33] At 0000 UTC on October 4, Nadine transitioned into an extratropical low-pressure area, while located about 195 miles (315 km) southwest of the central Azores. The low rapidly moved northeastward, degenerated into a trough of low pressure, and was absorbed by a cold front later that day.[1]
