a. Synoptic History

The genesis of Tropical Storm Nadine resulted from the interaction of a strong upper-level trough and a tropical wave. Water vapor imagery showed a distinct and nearly stationary upper-trough extending northeastward from the Leeward Islands across the Atlantic for several days. A cut-off low generated within the trough, moved southwestward, and interacted with a tropical wave that reached the area on 16 October. The system as a whole began to move slowly westward with increasing convection and on the 17th, a broad low to middle level circulation became apparent on visible images. However, it was not until the 19th, when the system became stationary, that ship reports indicated that a surface circulation had developed. It is estimated that a tropical depression formed about 600 nautical miles southeast of Bermuda at 1200 UTC 19 October.

The depression moved slowly northward and then northeastward around the periphery of the subtropical ridge and ahead of a cold front. The thunderstorm activity became better organized with increasing outflow while the shear relaxed. Based on satellite Dvorak intensity numbers, it is estimated that the depression became Tropical Storm Nadine at 1200 UTC on the 20th. Nadine reached a peak intensity of 58 mph and a minimum pressure of 999 mb at 0000 UTC on the 21st when a possible eye-like feature and an impressive outflow were observed on satellite imagery. Thereafter, the shear increased and convection began to weaken. Nadine interacted with a frontal zone and became a weak extratropical low at 0000 UTC 22 October while moving northeastward. It was then absorbed by a much larger frontal low.

b. Meteorological Statistics

A report of 38 mph from the southeast from the vessel Prince of Waves located just east of the cloud system center was used to initiate tropical depression advisories.

c. Casualty and Damage Statistics

No casualties or damages were associated with Nadine.
