A tropical wave formed in association with an area of disturbed weather accompanying an upper-level low about midway between the western coast of Africa and the Lesser Antilles on October 18. This interaction sporadically produced concentrated thunderstorm activity as it moved to the northwest over the next several days.
Atmospheric conditions improved markedly on October 21, and allowed the system to organize rapidly into Tropical Depression Nineteen on October 22. The cyclone began to curve towards the northeast later that day, as a front approached from the west. By late on October 23, convection had developed close enough to the center of circulation that the cyclone was upgraded to Tropical Storm Tony.
Despite shear from the front to its west, Tony experienced modest strengthening as it accelerated to the east-northeast, and the storm reached its peak intensity of 50 mph winds and a pressure of 1000 mb on October 24. Meanwhile, Tony was beginning to exhibit nontropical characteristics; the banding features became more linear, and the circulation elongated. The transition was very gradual, however, and the system remained a tropical storm through October 25, at which time it lost any remaining tropical characteristics and was downgraded to a remnant low.
