Tropical Depression One - June 22-28, 1992

A weak tropical wave crossed Dakar, Senegal on June 12th.  It moved westward across
the Atlantic uneventfully through the southern Windward Islands and northern South
America.  On the 20th, the wave became convectively active north of Colombia.  Under
the influence of Tropical Storm Celia in the eastern Pacific and an upper low in the Gulf
of Mexico, the convective system spread northward over the northwest Caribbean, Cuba,
the Yucatan peninsula, and Florida

During the 23rd and 24th, raob data indicated the formation of a mid-level low near 20N
85W.  When a plane investigated the area on the 24th, no low level center was found.   By
the afternoon of the 25th, ship reports and data buoys indicated a surface low had formed
which began the life cycle of Tropical Depression One.  The system experienced westerly
shear, as all the thunderstorm activity became well-removed from the low level center.  The
shear was caused by the upper low in the Gulf of Mexico and Celia in the Pacific Ocean.

The system made an arc north, then eastward, across the eastern Gulf of Mexico across
Florida before becoming absorbed into a large nontropical low in the western Atlantic.
Its track is below, which utilized a track produced by the National Hurricane Center.
